What are good command line HTTP clients?
|
||||
================================================================================
|
||||
The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux. In my view, one of Linux's biggest strengths is its synergy. The usefulness of Linux doesn't derive only from the huge raft of open source (command line) utilities. Instead, it's the synergy generated by using them together, sometimes in conjunction with larger applications.
|
||||
|
||||
The Unix philosophy spawned a "software tools" movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects.
|
||||
|
||||
Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well independently.
|
||||
|
||||
This article looks at 3 open source command line HTTP clients. These clients let you download files off the internet from a command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and cURL will be invaluable.

HTTPie (pronounced aych-tee-tee-pie) is an open source command line HTTP client. It is a a command line interface, cURL-like tool for humans.
|
||||
|
||||
The goal of this software is to make CLI interaction with web services as human-friendly as possible. It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

Linux FAQs with Answers--How to install autossh on Linux
|
||||
================================================================================
|
||||
> **Question**: I would like to install autossh on [insert your Linux distro]. How can I do that?
|
||||
|
||||
[autossh][1] is an open-source tool that allows you to monitor an SSH session and restart it automatically should it gets disconnected or stops forwarding traffic. autossh assumes that [passwordless SSH login][2] for a destination host is already setup, so that it can restart a broken SSH session without user's involvement.
|
||||
|
||||
autossh comes in handy when you want to set up [reverse SSH tunnels][3] or [mount remote folders over SSH][4]. Essentially in any situation where persistent SSH sessions are required, autossh can be useful.
|
||||
|
||||
|
||||
|
||||
Here is how to install autossh on various Linux distributions.
|
||||
|
||||
### Install Autossh on Debian or Ubuntu ###
|
||||
|
||||
autossh is available in base repositories of Debian based systems, so installation is easy.
|
||||
|
||||
$ sudo apt-get install autossh
|
||||
|
||||
### Install Autossh on Fedora ###
|
||||
|
||||
Fedora repositories also carry autossh package. So simply use yum command.
|
||||
|
||||
$ sudo yum install autossh
|
||||
|
||||
### Install Autossh on CentOS or RHEL ###
|
||||
|
||||
For CentOS/RHEL 6 or earlier, enable [Repoforge repository][5] first, and then use yum command.
|
||||
|
||||
$ sudo yum install autossh
|
||||
|
||||
For CentOS/RHEL 7, autossh is no longer available in Repoforge repository. You will need to build it from the source (explained below).
|
||||
|
||||
### Install Autossh on Arch Linux ###
|
||||
|
||||
$ sudo pacman -S autossh
|
||||
|
||||
### Compile Autossh from the Source on Debian or Ubuntu ###
|
||||
|
||||
If you would like to try the latest version of autossh, you can build it from the source as follows.
|
||||
|
||||
$ sudo apt-get install gcc make
|
||||
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
||||
$ tar -xf autossh-1.4e.tgz
|
||||
$ cd autossh-1.4e
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
|
||||
### Compile Autossh from the Source on CentOS, Fedora or RHEL ###
|
||||
|
||||
On CentOS/RHEL 7, autossh is not available as a pre-built package. So you'll need to compile it from the source as follows.
|
||||
|
||||
$ sudo yum install wget gcc make
|
||||
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
||||
$ tar -xf autossh-1.4e.tgz
|
||||
$ cd autossh-1.4e
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||

什么是好的命令行HTTP客户端?
|
||||
==============================================================================
|
||||
整体大于各部分之和,这是引自希腊哲学家和科学家的亚里士多德的名言。这句话特别切中Linux。在我看来，Linux最强大的地方之一就是它的协作性。Linux的实用性并不仅仅源自大量的开源程序（命令行）。相反，其协作性来自于这些程序的综合利用，有时是结合更大型的应用。
|
||||
|
||||
Unix哲学引发了一场“软件工具”的运动，关注开发简洁，基础，干净，模块化和扩展性好的代码，并可以运用于其他的项目。这种哲学为许多的Linux项目留下了一个重要的元素。
|
||||
|
||||
好的开源开发者写程序为了确保该程序尽可能运行正确，同时能与其他程序很好地协作。目标就是使用者拥有一堆方便的工具，每一个力求干不止一件事。许多程序能独立工作得很好。
|
||||
|
||||
这篇文章讨论3个开源命令行HTTP客户端。这些客户端可以让你使用命令行从互联网上下载文件。但同时，他们也可以用于许多有意思的地方，如测试，调式和与HTTP服务器或网络应用互动。对于HTTP架构师和API设计人员来说，使用命令行操作HTTP是一个值得花时间学习的技能。如果你需要来回使用API，HTTPie和cURL，这没什么价值。
|
||||

||||
|
||||
|
||||
|
||||
|
||||
|
||||
HTTPie（发音 aych-tee-tee-pie）是一款开源命令行HTTP客户端。它是一个命令行界面，类cURL的工具。
|
||||
|

安装Inkscape - 开源适量图形编辑器
|
||||
================================================================================
|
||||
Inkscape是一款开源矢量图形编辑工具，它使用可缩放矢量图形(SVG)图形格式并不同于它的竞争对手如Xara X、Corel Draw和Adobe Illustrator等等。SVG是一个广泛部署、免版税使用的图形格式，由W3C SVG工作组开发和维护。这是一个跨平台工具，完美运行于Linux、Windows和Mac OS上。
|
||||
|
||||
Inkscape始于2003年，起初它的bug跟踪系统托管于Sourceforge上但是 后来迁移到了Launchpad上。当前它最新的一个稳定版本是0.91，它不断地在发展和修改中。我们将在本文里了解一下它的突出特点和安装过程。
|
||||
|
||||

||||
让我们直接来了解这款应用程序的显著特性。
|
||||
|
||||
#### 创建对象 ####
|
||||
|
||||
- 用铅笔工具来画出不同颜色、大小和形状的手绘线，用贝塞尔曲线（笔式）工具来画出直线和曲线，通过书法工具来应用到手写的书法笔画上等等
|
||||
- 用文本工具来创建、选择、编辑和格式化文本。在纯文本框、在路径上或在形状里操作文本
|
||||

#### 渲染 ####
|
||||
|
||||
- Inkscape完全支持抗锯齿显示，这是一种通过柔化边界上的像素从而减少或消除凹凸锯齿的技术。
|
||||
- 支持alpha透明显示和PNG格式图片的导出
|
||||
|
||||
### 在Ubuntu 14.04和14.10上安装Inkscape ###
|
||||
|
||||
为了在Ubuntu上安装Inkscape，我们首先需要 [添加它的稳定版Personal Package Archive][1] (PPA) 至Advanced Package Tool (APT) 库中。打开终端并运行一下命令来添加它的PPA：
|
||||
|
||||
sudo add-apt-repository ppa:inkscape.dev/stable
|
||||
|
||||
|
||||
|
||||
PPA添加到APT库中后，我们要用以下命令进行更新：
|
||||
|
||||
sudo apt-get update
|
||||
|
||||
|
||||
|
||||
更新好库之后，我们准备用以下命令来完成安装：
|
||||
|
||||
sudo apt-get install inkscape
|
||||
|
||||
|
||||
|
||||
恭喜，现在Inkscape已经被安装好了，我们可以充分利用它的丰富功能特点来编辑制作图像了。
|
||||
|
||||
|
||||
|
||||
### 结论 ###
|
||||
|
||||
Inkscape是一款特点鲜明的图形编辑工具，它给予用户充分发挥自己艺术力的权利。它还是一款自由安装和自定义开源应用并且支持大范围文件类型包括JPEG, PNG, GIF和PDF且不仅这些。访问它的 [官方网站][2] 来获取更多新闻和应用更新。

Linux有问必答－－如何安装autossh
|
||||
================================================================================
|
||||
> **提问**: 我打算在linux上安装autossh，我应该怎么做呢?
|
||||
|
||||
[autossh][1] 是一款开源工具，可以帮助管理SSH会话，自动重连和停止转发流量。autossh会假定目标主机已经设定[无密码SSH登陆][2]，以便autossh可以重连断开的SSH会话而不用用户操作。
|
||||
|
||||
只要你建立[反向SSH隧道][3]或者[挂载基于SSH的远程文件夹][4]，autossh迟早会派上用场。基本上只要需要维持SSH会话，autossh肯定是有用的。
|
||||
|
||||
|
||||
|
||||
|
||||
下面有许多linux发行版autossh的安装方法。
|
||||
|
||||
### Debian 或 Ubuntu 系统 ###
|
||||
|
||||
autossh已经加入基于Debian系统的基础库，所以可以很方便的安装。
|
||||
|
||||
$ sudo apt-get install autossh
|
||||
|
||||
### Fedora 系统 ###
|
||||
|
||||
Fedora库同样包含autossh包，使用yum安装。
|
||||
|
||||
$ sudo yum install autossh
|
||||
|
||||
### CentOS 或 RHEL 系统 ###
|
||||
|
||||
CentOS/RHEL 6 或早期版本, 需要开启第三库[Repoforge库][5], 然后才能使用yum安装.
|
||||
|
||||
$ sudo yum install autossh
|
||||
|
||||
CentOS/RHEL 7以后,autossh 已经不在Repoforge库中. 你需要从源码编译安装（例子在下面）.
|
||||
|
||||
|
||||
### Arch Linux 系统 ###
|
||||
|
||||
$ sudo pacman -S autossh
|
||||
|
||||
### Debian 或 Ubuntu 系统中从源码编译安装###
|
||||
|
||||
如果你想要使用最新版本的autossh，你可以自己编译源码安装
|
||||
|
||||
$ sudo apt-get install gcc make
|
||||
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
||||
$ tar -xf autossh-1.4e.tgz
|
||||
$ cd autossh-1.4e
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
|
||||
### CentOS, Fedora 或 RHEL 系统中从源码编译安装###
|
||||
|
||||
在CentOS/RHEL 7以后，autossh不在是预编译包。所以你不得不从源码编译安装。
|
||||
|
||||
$ sudo yum install wget gcc make
|
||||
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
||||
$ tar -xf autossh-1.4e.tgz
|
||||
$ cd autossh-1.4e
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
