Today, I found out a similar utility called “undistract-me” that notifies you when long running terminal commands complete. Picture this scenario. You run a command that takes a while to finish. In the mean time, you check your facebook and get so involved in it. After a while, you remembered that you ran a command few minutes ago. You go back to the Terminal and notice that the command has already finished. But you have no idea when the command is completed. Have you ever been in this situation? I bet most of you were in this situation many times. This is where “undistract-me” comes in help. You don’t need to constantly check the terminal to see if a command is completed or not. Undistract-me utility will notify you when a long running command is completed. It will work on Arch Linux, Debian, Ubuntu and other Ubuntu-derivatives. - -#### Installing Undistract-me - -Undistract-me is available in the default repositories of Debian and its variants such as Ubuntu. All you have to do is to run the following command to install it. - -``` -sudo apt-get install undistract-me -``` - -The Arch Linux users can install it from AUR using any helper programs. - -Using [Pacaur][4]: - -``` -pacaur -S undistract-me-git -``` - -Using [Packer][5]: - -``` -packer -S undistract-me-git -``` - -Using [Yaourt][6]: - -``` -yaourt -S undistract-me-git -``` - -Then, run the following command to add “undistract-me” to your Bash. - -``` -echo 'source /etc/profile.d/undistract-me.sh' >> ~/.bashrc -``` - -Alternatively you can run this command to add it to your Bash: - -``` -echo "source /usr/share/undistract-me/long-running.bash\nnotify_when_long_running_commands_finish_install" >> .bashrc -``` - -If you are in Zsh shell, run this command: - -``` -echo "source /usr/share/undistract-me/long-running.bash\nnotify_when_long_running_commands_finish_install" >> .zshrc -``` - -Finally update the changes: - -For Bash: - -``` -source ~/.bashrc -``` - -For Zsh: - -``` -source ~/.zshrc -``` - -#### Configure Undistract-me - -By default, Undistract-me will consider any command that takes more than 10 seconds to complete as a long-running command. You can change this time interval by editing /usr/share/undistract-me/long-running.bash file. - -``` -sudo nano /usr/share/undistract-me/long-running.bash -``` - -Find “LONG_RUNNING_COMMAND_TIMEOUT” variable and change the default value (10 seconds) to something else of your choice. - - [![](http://www.ostechnix.com/wp-content/uploads/2017/11/undistract-me-1.png)][7] - -Save and close the file. Do not forget to update the changes: - -``` -source ~/.bashrc -``` - -Also, you can disable notifications for particular commands. To do so, find the “LONG_RUNNING_IGNORE_LIST” variable and add the commands space-separated like below. - -By default, the notification will only show if the active window is not the window the command is running in. That means, it will notify you only if the command is running in the background Terminal window. If the command is running in active window Terminal, you will not be notified. If you want undistract-me to send notifications either the Terminal window is visible or in the background, you can set IGNORE_WINDOW_CHECK to 1 to skip the window check. - -The other cool feature of Undistract-me is you can set audio notification along with visual notification when a command is done. By default, it will only send a visual notification. You can change this behavior by setting the variable UDM_PLAY_SOUND to a non-zero integer on the command line. However, your Ubuntu system should have pulseaudio-utils and sound-theme-freedesktop utilities installed to enable this functionality. - -Please remember that you need to run the following command to update the changes made. - -For Bash: - -``` -source ~/.bashrc -``` - -For Zsh: - -``` -source ~/.zshrc -``` - -It is time to verify if this really works. - -#### Get Notification When Long Running Terminal Commands Complete - -Now, run any command that takes longer than 10 seconds or the time duration you defined in Undistract-me script. - -I ran the following command on my Arch Linux desktop. - -``` -sudo pacman -Sy -``` - -This command took 32 seconds to complete. After the completion of the above command, I got the following notification. - - [![](http://www.ostechnix.com/wp-content/uploads/2017/11/undistract-me-2.png)][8] - -Please remember Undistract-me script notifies you only if the given command took more than 10 seconds to complete. If the command is completed in less than 10 seconds, you will not be notified. Of course, you can change this time interval settings as I described in the Configuration section above. - -I find this tool very useful. It helped me to get back to the business after I completely lost in some other tasks. I hope this tool will be helpful to you too. - -More good stuffs to come. Stay tuned! - -Cheers! - -Resource: - -* [Undistract-me GitHub Repository][1] - --------------------------------------------------------------------------------- - -via:

Many people already embrace Ansible. +让我们先休息一会儿，先去了解一个不同的东西：[Ansible][22] 的世界。你知道它吗？它棒极了，是吗？你不这么认为？好吧，是时候去学习一些新事物了。Ansible 是一个项目，它允许你通过写一些任务去管理你的基础设施，并在你选择的环境中运行它们。不需要去安装和设置任何的服务；你可以从你的笔记本电脑中去很很容易地做任何事情。许多人已经接受 Ansible 了。 -Imagine this scenario: You invested in Ansible, you wrote plenty of Ansible roles and playbooks that you use to manage your infrastructure, and you are thinking about investing in containers. What should you do? Start writing container image definitions via shell scripts and Dockerfiles? That doesn't sound right. +想像一下这样的场景：你在 Ansible 中，你写了很多的 Ansible 角色和 playbooks，你可以用它们去管理你的基础设施，并且想把它们运用到容器中。你应该怎么做？开始通过 shell 脚本和 Dockerfiles 去写容器镜像定义？听起来好像不对。 -Some people from the Ansible development team asked this question and realized that those same Ansible roles and playbooks that people wrote and use daily can also be used to produce container images. But not just that—they can be used to manage the complete lifecycle of containerized projects. From these ideas, the [Ansible Container][12] project was born. It utilizes existing Ansible roles that can be turned into container images and can even be used for the complete application lifecycle, from build to deploy in production. +来自 Ansible 开发团队的一些人问到这个问题，并且它们意识到，人们每天使用那些同样的 Ansible 角色和 playbooks 也可以用来制作容器镜像。但是 Ansible 能做到的不止这些 — 它可以被用于去管理容器化项目的完整的生命周期。从这些想法中，[Ansible Container][12] 项目诞生了。它使用已有的可以变成容器镜像的 Ansible 角色，甚至可以被用于应用程序在生产系统中从构建到部署的完整生命周期。 -Let's talk about the problems I mentioned regarding best practices in context of Dockerfiles. A word of warning: This is going to be very specific and technical. Here are the top three issues I have: +现在让我们讨论一下，在 Dockerfiles 环境中关于最佳实践时可能存在的问题。这里有一个警告：这将是非常具体且技术性的。出现最多的三个问题有： -### 1\.

It can be something like: +当写 Dockerfiles 时，你可以通过 **/bin/sh -c** 解释指定的脚本。它可以做类似这样的事情： ``` RUN dnf install -y nginx ``` -where RUN is a Dockerfile instruction and the rest are its arguments (which are passed to shell). But imagine a more complex scenario: +RUN 处是一个 Dockerfile 指令并且其它的都是参数（它传递给 shell）。但是，想像一个更复杂的场景： ``` RUN set -eux; \ @@ -51,36 +51,36 @@ RUN set -eux; \     echo "${goRelSha256} *go.tgz" | sha256sum -c -; \ ``` -This one is taken from [the official golang image][13]. It doesn't look pretty, right? +这仅是从 [the official golang image][13] 中拿来的一个。它看起来并不好看，是不是？ -### 2\. You can't parse Dockerfiles easily. +### 2\. 你解析 Dockerfiles 并不容易。 -Dockerfiles are a new format without a formal specification. This is tricky if you need to process Dockerfiles in your infrastructure (e.g., automate the build process a bit). The only specification is [the code][14] that is part of **dockerd**. The problem is that you can't use it as a library. The easiest solution is to write a parser on your own and hope for the best. Wouldn't it be better to use some well-known markup language, such as YAML or JSON? +Dockerfiles 是一个没有正式规范的新格式。如果你需要在你的基础设施（比如，让构建过程自动化一点）中去处理 Dockerfiles 将会很复杂。仅有的规划是 [这个代码][14]，它是 **dockerd** 的一部分。问题是你不能使用它作为一个库（library）。最容易的解决方案是你自己写一个解析器，然后祈祷它运行的很好。使用一些众所周知的标记语言不是更好吗？比如，YAML 或者 JSON。 -### 3\. It's hard to control. +### 3\. 管理困难。 -If you are familiar with the internals of container images, you may know that every image is composed of layers. Once the container is created, the layers are stacked onto each other (like pancakes) using union filesystem technology. The problem is, that you cannot explicitly control this layering—you can't say, "here starts a new layer." You are forced to change your Dockerfile in a way that may hurt readability. The bigger problem is that a set of best practices has to be followed to achieve optimal results—newcomers have a really hard time here. +如果你熟悉容器镜像的内部结构，你可能知道每个镜像是由层（layers）构成的。一旦容器被创建，这些层就使用联合文件系统技术堆叠在一起（像煎饼一样）。问题是，你并不能显式地管理这些层 — 你不能说，“这儿开始一个新层”，你被迫使用一种可读性不好的方法去改变你的 Dockerfile。最大的问题是，必须遵循一套最佳实践以去达到最优结果 — 新来的人在这个地方可能很困难。 -### Comparing Ansible language and Dockerfiles +### Ansible 语言和 Dockerfiles 比较 -The biggest shortcoming of Dockerfiles in comparison to Ansible is that Ansible, as a language, is much more powerful. For example, Dockerfiles have no direct concept of variables, whereas Ansible has a complete templating system (variables are just one of its features). Ansible contains a large number of modules that can be easily utilized, such as [**wait_for**][15], which can be used for service readiness checks—e.g., wait until a service is ready before proceeding. With Dockerfiles, everything is a shell script. So if you need to figure out service readiness, it has to be done with shell (or installed separately). The other problem with shell scripts is that, with growing complexity, maintenance becomes a burden. Plenty of people have already figured this out and turned those shell scripts into Ansible. +相比 Ansible，Dockerfiles 的最大缺点，也是 Ansible 的优点，作为一个语言，Ansible 更强大。例如，Dockerfiles 没有直接的变量概念，而 Ansible 有一个完整的模板系统（变量只是它其中的一个特性）。Ansible 包含了很多更易于使用的模块，比如，[**wait_for**][15]，它可以被用于服务就绪检查，比如，在处理之前等待服务准备就绪。在 Dockerfiles 中，做任何事情都通过一个 shell 脚本。因此，如果你想去找出已准备好的服务，它必须使用 shell（或者独立安装）去做。使用 shell 脚本的其它问题是，它会变得很复杂，维护成为一种负担。很多人已经找到了这个问题，并将这些 shell 脚本转到 Ansible。 -If you are interested in this topic and would like to know more, please come to [Open Source Summit][16] in Prague to see [my presentation][17] on Monday, Oct. 23, at 4:20 p.m. in Palmovka room. +如果你对这个主题感兴趣，并且想去了解更多内容，请访问 [Open Source Summit][16]，在 Prague 去看 [我的演讲][17]，时间是 10 月 23 日，星期一，4:20 p.m. 在 Palmovka room 中。 - _Learn more in Tomas Tomecek's talk, [From Dockerfiles to Ansible Container][7], at [Open Source Summit EU][8], which will be held October 23-26 in Prague._ + _看更多的 Tomas Tomecek 演讲，[从 Dockerfiles 到 Ansible Container][7]，在 [Open Source Summit EU][8]，它将在 10 月 23-26 日在 Prague 召开。_ -### About the author +### 关于作者 - [![human](https://opensource.com/sites/default/files/styles/profile_pictures/public/pictures/ja.jpeg?itok=4ATUEAbd)][18] Tomas Tomecek - Engineer.

The files are copied to a specific directory on the server that I run for a volunteer organization, from where the files can be downloaded and played. +我最近写了一个简短的 Bash 程序来将 MP3 文件从一台网络主机的 UBS 盘中拷贝到另一台网络主机上去。拷贝出来的文件存放在一台志愿者组织所属服务器的特定目录下， 在那里，这些文件可以被下载和播放。 -My program does a few other things, such as changing the name of the files before they are copied so they are automatically sorted by date on the webpage. It also deletes all the files on the USB drive after verifying that the transfer completed correctly. This nice little program has a few options, such as -h to display help, -t for test mode, and a couple of others. +我的程序还会做些其他事情，比如为了自动在网页上根据日期排序，在拷贝文件之前会先对这些文件重命名。 在验证拷贝完成后，还会删掉 USB 盘中的所有文件。 这个小程序还有一些其他选项，比如 `-h` 会显示帮助， `-t` 进入测试模式等等。 -My program, as wonderful as it is, must run as root to perform its primary functions. Unfortunately, this organization has only a few people who have any interest in administering our audio and computer systems, which puts me in the position of finding semi-technical people and training them to log into the computer used to perform the transfer and run this little program. +我的程序需要以 root 运行才能发挥作用。然而， 这个组织中之后很少的人对管理音频和计算机系统有兴趣的，这使得我不得不找那些半吊子的科技人员来，并培训他们登陆用于传输的计算机，运行这个小程序。 -It is not that I cannot run the program myself, but for various reasons, including travel and illness, I am not always there. Even when I am present, as the "lazy sysadmin," I like to have others do my work for me. So, I write scripts to automate those tasks and use sudo to anoint a couple of users to run the scripts. Many Linux commands require the user to be root in order to run. This protects the system against accidental damage, such as that caused by my own stupidity, and intentional damage by a user with malicious intent. +倒不是说我不能亲自运行这个程序，但由于外出和疾病等等各种原因， 我不是时常在场的。 即使我在场， 作为一名 "懒惰的系统管理员"， 我也希望别人能替我把事情给做了。 因此我写了一些脚本来自动完成这些人物并通过 sudo 来指定某些人来运行这些脚本。 很多 Linux 命令都需要用户以 root 身份来运行。 sudo 能够保护系统免遭一时糊涂造成的意外损坏以及恶意用户的故意破坏。 ### Do that sudo that you do so well -The sudo program is a handy tool that allows me as a sysadmin with root access to delegate responsibility for all or a few administrative tasks to other users of the computer. It allows me to perform that delegation without compromising the root password, thus maintaining a high level of security on the host. +sudo 是一个很方便的工具，它让我一个 root 管理员可以分配所有或者部分管理性的任务给其他用户， 而且还无需告诉他们 root 密码， 从而保证主机的高安全性。 -Let's assume, for example, that I have given regular user, "ruser," access to my Bash program, "myprog," which must be run as root to perform parts of its functions. First, the user logs in as ruser with their own password, then uses the following command to run myprog. +假设，我给了普通用户 "ruser" 访问我 Bash 程序 "myprog" 的权限， 而这个程序的部分功能需要 root 权限。 那么该用户可以以 ruser 的身份登陆，然后通过以下命令运行 myprog。 -``` - sudo myprog +```shell +sudo myprog ``` -I find it helpful to have the log of each command run by sudo for training. I can see who did what and whether they entered the command correctly. +我发现在训练时记录下每个用 sudo 执行的命令会很有帮助。我可以看到谁执行了哪些命令，他们是否输对了。 -I have done this to delegate authority to myself and one other user to run a single program; however, sudo can be used to do so much more. It can allow the sysadmin to delegate authority for managing network functions or specific services to a single person or to a group of trusted users. It allows these functions to be delegated while protecting the security of the root password. +我委派了权限给自己和另一个人来运行那个程序; 然而，sudo 可以做更多的事情。 它允许系统管理员委派网络管理或特定的服务器权限给某个人或某组人，以此来保护 root 密码的安全性。 -### Configuring the sudoers file +### 配置 sudoers 文件 -As a sysadmin, I can use the /etc/sudoers file to allow users or groups of users access to a single command, defined groups of commands, or all commands. This flexibility is key to both the power and the simplicity of using sudo for delegation. +作为一名系统管理员，我使用 `/etc/sudoers` 文件来设置某些用户或某些用户组可以访问某个命令，或某组命令，或所有命令。 这种灵活性是使用 sudo 进行委派时能兼顾功能与简易性的关键。 -I found the sudoers file very confusing at first, so below I have copied and deconstructed the entire sudoers file from the host on which I am using it. Hopefully it won't be quite so obscure for you by the time you get through this analysis. Incidentally, I've found that the default configuration files in Red Hat-based distributions tend to have lots of comments and examples to provide guidance, which makes things easier, with less online searching required. +我一开始对 `sudoers` 文件感到很困惑，因此下面我会拷贝并分解我所使用主机上的完整 `sudoers` 文件。 希望在分析的过程中不会让你感到困惑。 我意外地发现， 基于 Red Hat 的发行版中默认的配置文件都会很多注释以及例子来指导你如何做出修改，这使得修改配置文件变得简单了很多，也不需要在互联网上搜索那么多东西了。 -Do not use your standard editor to modify the sudoers file. Use the visudo command because it is designed to enable any changes as soon as the file is saved and you exit the editor. It is possible to use editors besides Vi in the same way as visudo. +不要直接用编辑起来修改 sudoers 文件，而应该用 `visudo` 命令，因为该命令会在你保存并退出编辑器后就立即生效这些变更。 visudo 也可以使用除了 `Vi` 之外的其他编辑器。 -Let's start analyzing this file at the beginning with a couple types of aliases. +让我们首先来分析一下文件中的各种别名。 -### Host aliases +#### Host aliases(主机别名) -The host aliases section is used to create groups of hosts on which commands or command aliases can be used to provide access. The basic idea is that this single file will be maintained for all hosts in an organization and copied to /etc of each host. Some hosts, such as servers, can thus be configured as a group to give some users access to specific commands, such as the ability to start and stop services like HTTPD, DNS, and networking; to mount filesystems; and so on. +host aliases 用于创建主机分组，在不同主机上可以设置允许访问不同的命令或命令别名 (command aliases)。 它的基本思想是，该文件由组织中的所有主机共同维护，然后拷贝到每台主机中的 `/etc` 中。 其中有些主机， 例如各种服务器， 可以配置成一个组来赋予用户访问特定命令的权限， 比如可以启停类似 HTTPD， DNS， 以及网络服务; 可以挂载文件系统等等。 -IP addresses can be used instead of host names in the host aliases. +在设置主机别名时也可以用 IP 地址替代主机名。 ``` ## Sudoers allows particular users to run various commands as -## the root user, without needing the root password. +## the root user，without needing the root password。 ## ## Examples are provided at the bottom of the file for collections -## of related commands, which can then be delegated out to particular -## users or groups. +## of related commands，which can then be delegated out to particular +## users or groups。 ## -## This file must be edited with the 'visudo' command. +## This file must be edited with the 'visudo' command。 ## Host Aliases -## Groups of machines.

If you already have a group defined there that meets your needs, such as "audio," use that group name preceded by a % sign like so: %audio when assigning commands that will be made available to groups later in the sudoers file. +正如 `sudoers` 文件中所阐明的，也可以直接使用 `/etc/groups` 中定义的组而不用自己设置别名。 如果你定义好的组(假设组名为 "audio")已经能满足要求了， 那么在后面分配命令时只需要在组名前加上 `%` 号，像这样: %audio。 -### Command aliases +#### Command aliases(命令别名) -Further down in the sudoers file is a command aliases section. These aliases are lists of related commands, such as networking commands or commands required to install updates or new RPM packages. These aliases allow the sysadmin to easily permit access to groups of commands. +再后面是 command aliases 部分。这些别名表示的是一系列相关的命令， 比如网络相关命令，或者 RPM 包管理命令。 这些别名允许系统管理员方便地为一组命令分配权限。 -A number of aliases are already set up in this section that make it easy to delegate access to specific types of commands. +该部分内容已经设置好了许多别名，这使得分配权限给某类命令变得方便很多。 -### Environment defaults +#### Environment defaults(环境默认值) -The next section sets some default environment variables. The item that is most interesting in this section is the !visiblepw line, which prevents sudo from running if the user environment is set to show the password. This is a security precaution that should not be overridden. +下部分内容设置默认的环境变量。这部分最值得关注的是 `！visiblepw` 这一行， 它表示当用户环境设置成显示密码时禁止 `sudo` 的运行。 这个安全措施不应该被修改掉。 -### Command section +#### Command section(命令部分) -The command section is the main part of the sudoers file. Everything you need to do can be done without all the aliases by adding enough entries here. The aliases just make it a whole lot easier. +command 部分是 `sudoers` 文件的主体。不使用别名并不会影响你完成要实现 的效果。 它只是让整个配置工作大幅简化而已。 -This section uses the aliases you've already defined to tell sudo who can do what on which hosts. The examples are self-explanatory once you understand the syntax in this section. Let's look at the syntax that we find in the command section. +这部分使用之前定义的别名来告诉 `sudo` 哪些人可以在哪些机器上执行哪些操作。一旦你理解了这部分内容的语法，你会发现这些例子都非常的直观。 下面我们来看看它的语法。 ``` ruser ALL=(ALL) ALL ``` -This is a generic entry for our user, ruser. The first ALL in the line indicates that this rule applies on all hosts. The second ALL allows ruser to run commands as any other user. By default, commands are run as root user, but ruser can specify on the sudo command line that a program be run as any other user. The last ALL means that ruser can run all commands without restriction. This would effectively make ruser root. +这是一条为用户 ruser 做出的配置。行中第一个 `ALL` 表示该条规则在所有主机上生效。 第二个 `ALL` 允许 ruser 以其他用户的身份运行命令。 默认情况下， 命令以 root 用户的身份运行， 但 ruser 可以在 sudo 命令行指定程序以其他用户的身份运行。 最后这个 ALL 表示 ruser 可以运行所有命令而不受限制。 这让 ruser 实际上就变成了 root。 -Note that there is an entry for root, as shown below. This allows root to have all-encompassing access to all commands on all hosts. +注意到下面还有一条针对 root 的配置。这允许 root 能通过 sudo 在任何主机上运行任何命令。 ``` root ALL=(ALL) ALL ``` -To try this out, I commented out the line and, as root, tried to run chown without sudo. That did work—much to my surprise. Then I used sudo chown and that failed with the message, "Root is not in the sudoers file. This incident will be reported." This means that root can run everything as root, but nothing when using the sudo command. This would prevent root from running commands as other users via the sudo command, but root has plenty of ways around that restriction. +为了实验一下效果，我注释掉了这行， 然后以 root 的身份， 试着直接运行 chown。 出乎意料的是这样是能成功的。 然后我试了下 sudo chown，结果失败了，提示信息 "Root is not in the sudoers file。 This incident will be reported"。 也就是说 root 可以直接运行任何命令， 但当加上 sudo 时则不行。 这会阻止 root 像其他用户一样使用 sudo 命令来运行其他命令， 但是 root 有太多中方法可以绕过这个约束了。 -The code below is the one I added to control access to myprog. It specifies that users who are listed in the AUDIO group, as defined near the top of the sudoers file, have access to only one program, myprog, on one host, guest1. +下面这行是我新增来控制访问 myprog 的。它指定了只有上面定义的 AUDIO 组中的用户才能在 guest1 这台主机上使用 myprog 这个命令。 ``` AUDIO guest1=/usr/local/bin/myprog ``` -Note that the syntax of the line above specifies only the host on which this access is to be allowed and the program. It does not specify that the user may run the program as any other user. +注意，上面这一行只指定了允许访问的主机名和程序， 而没有说用户可以以其他用户的身份来运行该程序。 -### Bypassing passwords +#### 省略密码 -You can also use NOPASSWORD to allow the users specified in the group AUDIO to run myprog without the need for entering their passwords. Here's how: +你也可以通过 NOPASSWORD 来让 AUDIO 组中的用户无需密码就能运行 myprog。像这样 Here's how: ``` AUDIO guest1=NOPASSWORD : /usr/local/bin/myprog ``` -I did not do this for my program, because I believe that users with sudo access must stop and think about what they are doing, and this may help a bit with that. I used the entry for my little program as an example. +我并没有这样做，因为哦我觉得使用 sudo 的用户必须要停下来想清楚他们正在做的事情，这对他们有好处。 我这里只是举个例子。 -### wheel +#### wheel -The wheel specification in the command section of the sudoers file, as shown below, allows all users in the "wheel" group to run all commands on any host. The wheel group is defined in the /etc/group file, and users must be added to the group there for this to work. The % sign preceding the group name means that sudo should look for that group in the /etc/group file. +`sudoers` 文件中命令部分的 `wheel` 说明(如下所示)允许所有在 "wheel" 组中的用户在任何机器上运行任何命令。wheel 组在 `/etc/group` 文件中定义， 用户必须加入该组后才能工作。 组名前面的 % 符号表示 sudo 应该去 `/etc/group` 文件中查找该组。 ``` %wheel ALL = (ALL) ALL ``` -This is a good way to delegate full root access to multiple users without providing the root password. Just adding a user to the wheel group gives them access to full root powers. It also provides a means to monitor their activities via the log entries created by sudo. Some distributions, such as Ubuntu, add users' IDs to the wheel group in /etc/group, which allows them to use the sudo command for all privileged commands. +这种方法很好的实现了为多个用户赋予完全的 root 权限而不用提供 root 密码。只需要把哦嗯虎加入 wheel 组中就能给他们提供完整的 root 的能力。 它也提供了一个种通过 sudo 创建的日志来监控他们行为的途径。 有些 Linux 发行版， 比如 Ubuntu， 会自动将用户的 ID 加入 `/etc/group` 中的 wheel 组中， 这使得他们能够用 sudo 命令运行所有的特权命令。 -### Final thoughts +### 结语 -I have used sudo here for a very limited objective—providing one or two users with access to a single command. I accomplished this with two lines (if you ignore my own comments). Delegating authority to perform certain tasks to users who do not have root access is simple and can save you, as a sysadmin, a good deal of time. It also generates log entries that can help detect problems. +我这里只是小试了一把 sudo — 我只是给一到两个用户以 root 权限运行单个命令的权限。完成这些只添加了两行配置(不考虑注释)。 将某项任务的权限委派给其他非 root 用户非常简单，而且可以节省你大量的时间。 同时它还会产生日志来帮你发现问题。 + +`sudoers` 文件还有许多其他的配置和能力。查看 sudo 和 sudoers 的 man 手册可以深入了解详细信息。 -The sudoers file offers a plethora of capabilities and options for configuration. Check the man files for sudo and sudoers for the down-and-dirty details. -------------------------------------------------------------------------------- From f48e6defcc1040148bf099b5ffe986f08c029e52 Mon Sep 17 00:00:00 2001 From: darksun Date: Thu, 7 Dec 2017 16:00:20 +0800 Subject: [PATCH 26/33] move to translated --- .../tech/20171205 Using sudo to delegate permissions in Linux.md | 0 1 file changed, 0 insertions(+), 0 deletions(-) rename {sources => translated}/tech/20171205 Using sudo to delegate permissions in Linux.md (100%) diff --git a/sources/tech/20171205 Using sudo to delegate permissions in Linux.md b/translated/tech/20171205 Using sudo to delegate permissions in Linux.md similarity index 100% rename from sources/tech/20171205 Using sudo to delegate permissions in Linux.md rename to translated/tech/20171205 Using sudo to delegate permissions in Linux.md From 2a75d325e3a725248eabf27f2d78f5512e399cd6 Mon Sep 17 00:00:00 2001 From: darksun Date: Thu, 7 Dec 2017 16:12:11 +0800 Subject: [PATCH 27/33] =?UTF-8?q?=E9=80=89=E9=A2=98:=20Suplemon=20-=20Mode?= =?UTF-8?q?rn=20CLI=20Text=20Editor=20with=20Multi=20Cursor=20Support?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...I Text Editor with Multi Cursor Support.md | 151 ++++++++++++++++++ 1 file changed, 151 insertions(+) create mode 100644 sources/tech/20171129 Suplemon - Modern CLI Text Editor with Multi Cursor Support.md diff --git a/sources/tech/20171129 Suplemon - Modern CLI Text Editor with Multi Cursor Support.md b/sources/tech/20171129 Suplemon - Modern CLI Text Editor with Multi Cursor Support.md new file mode 100644 index 0000000000..2b82be93ba --- /dev/null +++ b/sources/tech/20171129 Suplemon - Modern CLI Text Editor with Multi Cursor Support.md @@ -0,0 +1,151 @@ +Suplemon - Modern CLI Text Editor with Multi Cursor Support +====== +Suplemon is a modern text editor for CLI that emulates the multi cursor behavior and other features of [Sublime Text][1].

Not everyone knows what a particular command or program will do. Of course, you can check it with [Explainshell][2]. You need to copy/paste the command in Explainshell website and it let you know what each part of a Linux command does. However, it is not necessary. Now, we can easily know what a command or program will exactly do before executing it, right from the Terminal. Say hello to “maybe”, a simple tool that allows you to run a command and see what it does to your files without actually doing it! After reviewing the output listed, you can then decide whether you really want to run it or not. + +#### How “maybe” works? + +According to the developer, + +> “maybe” runs processes under the control of ptrace with the help of python-ptrace library. When it intercepts a system call that is about to make changes to the file system, it logs that call, and then modifies CPU registers to both redirect the call to an invalid syscall ID (effectively turning it into a no-op) and set the return value of that no-op call to one indicating success of the original call. As a result, the process believes that everything it is trying to do is actually happening, when in reality nothing is. + +Warning: You should be very very careful when using this utility in a production system or in any systems you care about. It can still do serious damages, because it will block only a handful of syscalls. + +#### Installing “maybe” + +Make sure you have installed pip in your Linux system. If not, install it as shown below depending upon the distribution you use. + +On Arch Linux and its derivatives like Antergos, Manjaro Linux, install pip using the following command: + +``` +sudo pacman -S python-pip +``` + +On RHEL, CentOS: + +``` +sudo yum install epel-release +``` + +``` +sudo yum install python-pip +``` + +On Fedora: + +``` +sudo dnf install epel-release +``` + +``` +sudo dnf install python-pip +``` + +On Debian, Ubuntu, Linux Mint: + +``` +sudo apt-get install python-pip +``` + +On SUSE, openSUSE: + +``` +sudo zypper install python-pip +``` + +Once pip installed, run the following command to install “maybe”. + +``` +sudo pip install maybe +``` + +#### Know What A Command Or Program Will Exactly Do Before Executing It + +Usage is absolutely easy!

Modified by Opensource.com. [CC BY-SA 4.0][16] + +One of the challenges (among the many advantages) of being a sysadmin is running tasks when you'd rather be sleeping. For example, some tasks (including regularly recurring tasks) need to run overnight or on weekends, when no one is expected to be using computer resources. I have no time to spare in the evenings to run commands and scripts that have to operate during off-hours. And I don't want to have to get up at oh-dark-hundred to start a backup or major update. + +Instead, I use two service utilities that allow me to run commands, programs, and tasks at predetermined times. The [cron][17] and at services enable sysadmins to schedule tasks to run at a specific time in the future. The at service specifies a one-time task that runs at a certain time. The cron service can schedule tasks on a repetitive basis, such as daily, weekly, or monthly. + +In this article, I'll introduce the cron service and how to use it. + +### Common (and uncommon) cron uses + +I use the cron service to schedule obvious things, such as regular backups that occur daily at 2 a.m. I also use it for less obvious things. + +* The system times (i.e., the operating system time) on my many computers are set using the Network Time Protocol (NTP). While NTP sets the system time, it does not set the hardware time, which can drift. I use cron to set the hardware time based on the system time. + +* I also have a Bash program I run early every morning that creates a new "message of the day" (MOTD) on each computer. It contains information, such as disk usage, that should be current in order to be useful. + +* Many system processes and services, like [Logwatch][1], [logrotate][2], and [Rootkit Hunter][3], use the cron service to schedule tasks and run programs every day. + +The crond daemon is the background service that enables cron functionality. + +The cron service checks for files in the /var/spool/cron and /etc/cron.d directories and the /etc/anacrontab file. The contents of these files define cron jobs that are to be run at various intervals. The individual user cron files are located in /var/spool/cron, and system services and applications generally add cron job files in the /etc/cron.ddirectory. The /etc/anacrontab is a special case that will be covered later in this article. + +### Using crontab + +The cron utility runs based on commands specified in a cron table (crontab). Each user, including root, can have a cron file. These files don't exist by default, but can be created in the /var/spool/cron directory using the crontab -e command that's also used to edit a cron file (see the script below). I strongly recommend that you not use a standard editor (such as Vi, Vim, Emacs, Nano, or any of the many other editors that are available). Using the crontab command not only allows you to edit the command, it also restarts the crond daemon when you save and exit the editor. The crontabcommand uses Vi as its underlying editor, because Vi is always present (on even the most basic of installations). + +New cron files are empty, so commands must be added from scratch. I added the job definition example below to my own cron files, just as a quick reference, so I know what the various parts of a command mean. Feel free to copy it for your own use. + +``` +# crontab -e +SHELL=/bin/bash +MAILTO=root@example.com +PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin + +# For details see man 4 crontabs + +# Example of job definition: +# .---------------- minute (0 - 59) +# | .------------- hour (0 - 23) +# | | .---------- day of month (1 - 31) +# | | | .------- month (1 - 12) OR jan,feb,mar,apr ... +# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat +# | | | | | +# * * * * * user-name command to be executed + +# backup using the rsbu program to the internal 4TB HDD and then 4TB external +01 01 * * * /usr/local/bin/rsbu -vbd1 ; /usr/local/bin/rsbu -vbd2 + +# Set the hardware clock to keep it in sync with the more accurate system clock +03 05 * * * /sbin/hwclock --systohc + +# Perform monthly updates on the first of the month +# 25 04 1 * * /usr/bin/dnf -y update +``` + +The first three lines in the code above set up a default environment. The environment must be set to whatever is necessary for a given user because cron does not provide an environment of any kind. The SHELL variable specifies the shell to use when commands are executed. This example specifies the Bash shell. The MAILTO variable sets the email address where cron job results will be sent. These emails can provide the status of the cron job (backups, updates, etc.) and consist of the output you would see if you ran the program manually from the command line. The third line sets up the PATH for the environment. Even though the path is set here, I always prepend the fully qualified path to each executable. + +There are several comment lines in the example above that detail the syntax required to define a cron job. I'll break those commands down, then add a few more to show you some more advanced capabilities of crontab files. + +``` +01 01 * * * /usr/local/bin/rsbu -vbd1 ; /usr/local/bin/rsbu -vbd2 +``` + +This line runs my self-written Bash shell script, rsbu, that backs up all my systems. This job kicks off at 1:01 a.m. (01 01) every day. The asterisks (*) in positions three, four, and five of the time specification are like file globs, or wildcards, for other time divisions; they specify "every day of the month," "every month," and "every day of the week." This line runs my backups twice; one backs up to an internal dedicated backup hard drive, and the other backs up to an external USB drive that I can take to the safe deposit box. + +The following line sets the hardware clock on the computer using the system clock as the source of an accurate time. This line is set to run at 5:03 a.m. (03 05) every day. + +``` +03 05 * * * /sbin/hwclock --systohc +``` + +I was using the third and final cron job (commented out) to perform a dnf or yumupdate at 04:25 a.m. on the first day of each month, but I commented it out so it no longer runs. + +``` +# 25 04 1 * * /usr/bin/dnf -y update +``` + +### Other scheduling tricks + +Now let's do some things that are a little more interesting than these basics. Suppose you want to run a particular job every Thursday at 3 p.m.: + +``` +00 15 * * Thu /usr/local/bin/mycronjob.sh +``` + +Or, maybe you need to run quarterly reports after the end of each quarter. The cron service has no option for "The last day of the month," so instead you can use the first day of the following month, as shown below. (This assumes that the data needed for the reports will be ready when the job is set to run.) + +``` +02 03 1 1,4,7,10 * /usr/local/bin/reports.sh +``` + +The following shows a job that runs one minute past every hour between 9:01 a.m. and 5:01 p.m. + +``` +01 09-17 * * * /usr/local/bin/hourlyreminder.sh +``` + +I have encountered situations where I need to run a job every two, three, or four hours. That can be accomplished by dividing the hours by the desired interval, such as */3 for every three hours, or 6-18/3 to run every three hours between 6 a.m. and 6 p.m. Other intervals can be divided similarly; for example, the expression */15 in the minutes position means "run the job every 15 minutes." + +``` +*/5 08-18/2 * * * /usr/local/bin/mycronjob.sh +``` + +One thing to note: The division expressions must result in a remainder of zero for the job to run. That's why, in this example, the job is set to run every five minutes (08:05, 08:10, 08:15, etc.) during even-numbered hours from 8 a.m. to 6 p.m., but not during any odd-numbered hours. For example, the job will not run at all from 9 p.m. to 9:59 a.m. + +I am sure you can come up with many other possibilities based on these examples. + +### Limiting cron access + +More Linux resources + +* [What is Linux?][4] + +* [What are Linux containers?][5] + +* [Download Now: Linux commands cheat sheet][6] + +* [Advanced Linux commands cheat sheet][7] + +* [Our latest Linux articles][8] + +Regular users with cron access could make mistakes that, for example, might cause system resources (such as memory and CPU time) to be swamped. To prevent possible misuse, the sysadmin can limit user access by creating a + +**/etc/cron.allow** + + file that contains a list of all users with permission to create cron jobs. The root user cannot be prevented from using cron. + +By preventing non-root users from creating their own cron jobs, it may be necessary for root to add their cron jobs to the root crontab. "But wait!" you say. "Doesn't that run those jobs as root?" Not necessarily. In the first example in this article, the username field shown in the comments can be used to specify the user ID a job is to have when it runs. This prevents the specified non-root user's jobs from running as root. The following example shows a job definition that runs a job as the user "student": + +``` +04 07 * * * student /usr/local/bin/mycronjob.sh +``` + +### cron.d + +The directory /etc/cron.d is where some applications, such as [SpamAssassin][18] and [sysstat][19], install cron files. Because there is no spamassassin or sysstat user, these programs need a place to locate cron files, so they are placed in /etc/cron.d. + +The /etc/cron.d/sysstat file below contains cron jobs that relate to system activity reporting (SAR). These cron files have the same format as a user cron file. + +``` +# Run system activity accounting tool every 10 minutes +*/10 * * * * root /usr/lib64/sa/sa1 1 1 +# Generate a daily summary of process accounting at 23:53 +53 23 * * * root /usr/lib64/sa/sa2 -A +``` + +The sysstat cron file has two lines that perform tasks. The first line runs the sa1program every 10 minutes to collect data stored in special binary files in the /var/log/sadirectory. Then, every night at 23:53, the sa2 program runs to create a daily summary. + +### Scheduling tips + +Some of the times I set in the crontab files seem rather random—and to some extent they are. Trying to schedule cron jobs can be challenging, especially as the number of jobs increases. I usually have only a few tasks to schedule on each of my computers, which is simpler than in some of the production and lab environments where I have worked. + +One system I administered had around a dozen cron jobs that ran every night and an additional three or four that ran on weekends or the first of the month. That was a challenge, because if too many jobs ran at the same time—especially the backups and compiles—the system would run out of RAM and nearly fill the swap file, which resulted in system thrashing while performance tanked, so nothing got done. We added more memory and improved how we scheduled tasks. We also removed a task that was very poorly written and used large amounts of memory. + +The crond service assumes that the host computer runs all the time. That means that if the computer is turned off during a period when cron jobs were scheduled to run, they will not run until the next time they are scheduled. This might cause problems if they are critical cron jobs. Fortunately, there is another option for running jobs at regular intervals: anacron. + +### anacron + +The [anacron][20] program performs the same function as crond, but it adds the ability to run jobs that were skipped, such as if the computer was off or otherwise unable to run the job for one or more cycles. This is very useful for laptops and other computers that are turned off or put into sleep mode. + +As soon as the computer is turned on and booted, anacron checks to see whether configured jobs missed their last scheduled run. If they have, those jobs run immediately, but only once (no matter how many cycles have been missed). For example, if a weekly job was not run for three weeks because the system was shut down while you were on vacation, it would be run soon after you turn the computer on, but only once, not three times. + +The anacron program provides some easy options for running regularly scheduled tasks. Just install your scripts in the /etc/cron.[hourly|daily|weekly|monthly]directories, depending how frequently they need to be run. + +How does this work? The sequence is simpler than it first appears. + +1. The crond service runs the cron job specified in /etc/cron.d/0hourly. + +``` +# Run the hourly jobs +SHELL=/bin/bash +PATH=/sbin:/bin:/usr/sbin:/usr/bin +MAILTO=root +01 * * * * root run-parts /etc/cron.hourly +``` + +1. The cron job specified in /etc/cron.d/0hourly runs the run-parts program once per hour. + +2. The run-parts program runs all the scripts located in the /etc/cron.hourlydirectory. + +3. The /etc/cron.hourly directory contains the 0anacron script, which runs the anacron program using the /etdc/anacrontab configuration file shown here. + +``` +# /etc/anacrontab: configuration file for anacron + +# See anacron(8) and anacrontab(5) for details. + +SHELL=/bin/sh +PATH=/sbin:/bin:/usr/sbin:/usr/bin +MAILTO=root +# the maximal random delay added to the base delay of the jobs +RANDOM_DELAY=45 +# the jobs will be started during the following hours only +START_HOURS_RANGE=3-22 + +#period in days delay in minutes job-identifier command +1 5 cron.daily nice run-parts /etc/cron.daily +7 25 cron.weekly nice run-parts /etc/cron.weekly +@monthly 45 cron.monthly nice run-parts /etc/cron.monthly +``` + +1. The anacron program runs the programs located in /etc/cron.daily once per day; it runs the jobs located in /etc/cron.weekly once per week, and the jobs in cron.monthly once per month. Note the specified delay times in each line that help prevent these jobs from overlapping themselves and other cron jobs. + +Instead of placing complete Bash programs in the cron.X directories, I install them in the /usr/local/bin directory, which allows me to run them easily from the command line. Then I add a symlink in the appropriate cron directory, such as /etc/cron.daily. + +The anacron program is not designed to run programs at specific times. Rather, it is intended to run programs at intervals that begin at the specified times, such as 3 a.m. (see the START_HOURS_RANGE line in the script just above) of each day, on Sunday (to begin the week), and on the first day of the month. If any one or more cycles are missed, anacron will run the missed jobs once, as soon as possible. + +### More on setting limits + +I use most of these methods for scheduling tasks to run on my computers. All those tasks are ones that need to run with root privileges. It's rare in my experience that regular users really need a cron job. One case was a developer user who needed a cron job to kick off a daily compile in a development lab. + +It is important to restrict access to cron functions by non-root users. However, there are circumstances when a user needs to set a task to run at pre-specified times, and cron can allow them to do that. Many users do not understand how to properly configure these tasks using cron and they make mistakes. Those mistakes may be harmless, but, more often than not, they can cause problems. By setting functional policies that cause users to interact with the sysadmin, individual cron jobs are much less likely to interfere with other users and other system functions. + +It is possible to set limits on the total resources that can be allocated to individual users or groups, but that is an article for another time. + +For more information, the man pages for [cron][21], [crontab][22], [anacron][23], [anacrontab][24], and [run-parts][25] all have excellent information and descriptions of how the cron system works. + +### Topics + + [Linux][26][SysAdmin][27] + +### About the author + + [![](https://opensource.com/sites/default/files/styles/profile_pictures/public/david-crop.jpg?itok=oePpOpyV)][28] David Both + +- + + David Both is a Linux and Open Source advocate who resides in Raleigh, North Carolina.

It provides list of all connections that are currently established or are in waiting state. This tool is extremely useful in identifying the port numbers on which an application is working and we can also make sure if an application is working or not on the port it is supposed to work. +Netstat 是一个告诉我们系统中所有 tcp/udp/unix socket 连接状态的命令行工具。它会列出所有已经连接或者等待连接状态的连接。 该工具在识别某个应用监听哪个端口时特别有用，我们也能用它来判断某个应用是否正常的在监听某个端口。 -Netstat command also displays various other network related information such as routing tables, interface statistics, masquerade connections, multicast memberships etc., +Netstat 命令还能显示其他各种各样的网络相关信息，例如路由表， 网卡统计信息， 虚假连接以及多播成员等。 -In this tutorial, we will learn about Netstat with examples. +本文中，我们会通过几个例子来学习 Netstat。 -(Recommended Read: [Learn to use CURL command with examples][1] ) +(推荐阅读: [Learn to use CURL command with examples][1] ) Netstat with examples ============================================================ -### 1- Checking all connections - -To list out all the connections on a system, we can use ‘a’ option with netstat command, +### 1- 检查所有的连接 +使用 `a` 选项可以列出系统中的所有连接， +```shell $ netstat -a +``` -This will produce all tcp, udp & unix connections from the system. +这会显示系统所有的 tcp，udp 以及 unix 连接。 -### 2- Checking all tcp or udp or unix socket connections +### 2- 检查所有的 tcp/udp/unix socket 连接 -To list only the tcp connections our system, use ‘t’ options with netstat, +使用 `t` 选项只列出 tcp 连接， +```shell $ netstat -at +``` -Similarly to list out only the udp connections on our system, we can use ‘u’ option with netstat, +类似的，使用 `u` 选项只列出 udp 连接 to list out only the udp connections on our system， we can use ‘u’ option with netstat， +```shell $ netstat -au +``` -To only list out Unix socket connections, we can use ‘x’ options, +使用 `x` 选项只列出 Unix socket 连接，we can use ‘x’ options， +```shell $ netstat -ax +``` -### 3- List process id/Process Name with +### 3- 同时列出进程 ID/进程名称 -To get list of all connections along with PID or process name, we can use ‘p’ option & it can be used in combination with any other netstat option, +使用 `p` 选项可以在列出连接的同时也显示 PID 或者进程名称，而且它还能与其他选项连用， +```shell $ netstat -ap +``` -### 4- List only port number & not the name +### 4- 列出端口号而不是服务名 -To speed up our output, we can use ‘n’ option as it will perform any reverse lookup & produce output with only numbers.
