Betty：通过大白话执行Linux命令
|
||
================================================================================
|
||
|
||
**Betty** 是一个将类英语短语翻译成Linux命令的开源工具。这个项目的主要目的是让大家可以通过输入自然语言来使用强大的Linux系统。让我们来看一下它是怎么工作的。
|
||
|
||
### 安装 ###
|
||
|
||
Betty的安装非常简单直接。首先确认你已经安装了下面这些依赖包[LCTT译注，需要安装至少Ruby1.9以上版本]。
|
||
|
||
#### 对于基于Debian的系统：####
|
||
|
||
sudo apt-get install git curl ruby
|
||
|
||
####对于基于RPM的系统：####
|
||
|
||
yum install git curl ruby
|
||
|
||
现在用git工具把Betty库clone到你自定义的任何路径。这里我克隆到我的home目录，**例如 /home/sk/**.
|
||
|
||
git clone https://github.com/pickhardt/betty
|
||
|
||
添加betty的别名到你的bashrc配置文件。
|
||
|
||
sudo nano ~/.bashrc
|
||
|
||
将下列行添加到文件的末尾：
|
||
|
||
alias betty="/home/sk/betty/main.rb"
|
||
|
||
确保你已经正确地设置好了betty的路径。
|
||
|
||
好了，现在是时候和betty好好地玩耍了。
|
||
|
||
### 用法 ###
|
||
|
||
你应该在英语短语之前加上单词“betty” [LCTT译注，你自然可以用你的小甜心的名字来替换这个不是知道是谁的Betty :>]。你也许已经知道，如果我们想知道在系统中我们的用户名，应该运行下面的命令：
|
||
|
||
whoami
|
||
|
||
输出是这样的：
|
||
|
||
sk
|
||
|
||
如你所见，我当前登录的用户名是 **sk**. 现在我也可以通过下面的betty命令获取相同的结果。
|
||
|
||
betty whats my username
|
||
|
||
输出是这样的：
|
||
|
||
Betty: Running whoami
|
||
sk
|
||
|
||
真的好酷，是不是？Betty理解我输入的“whats my username”短语，然后运行“whoami”命令，最后输出结果。
|
||
|
||
让我们也来看其他命令。
|
||
|
||
如果你的输入不够准确，Betty也能以多种方式回应你。例如，我们运行下面的命令：
|
||
|
||
betty whats my name
|
||
|
||
Betty不确定她应该查找系统用户名还是用户全名。这种情况下，她会询问你多个问题来找到准确的结果。如你下面所见，Betty问我想要运行哪一条命令（whoami 还是 finger $(whoami) | sed 's/.*:*//;q')[LCTT译注，需要你的系统已经安装finger]。我只想知道我的用户名，所以我选择数字**1**。
|
||
|
||
Betty: Okay, I have multiple ways to respond.
|
||
Betty: Enter the number of the command you want me to run, or N (no) if you don't want me to run any.
|
||
[1] whoami
|
||
Gets your system username.
|
||
[2] finger $(whoami) | sed 's/.*: *//;q'
|
||
Gets your full name.
|
||
1
|
||
Betty: Running whoami
|
||
sk
|
||
|
||
### 压缩和解压缩文件夹 ###
|
||
|
||
如果你想要压缩一个文件或者文件夹，用下面的命令。例如，我想压缩我home目录下的“test”文件夹。
|
||
|
||
betty compress test/ test.tar.gz
|
||
|
||
输出是这样的：
|
||
|
||
Betty: Running tar -czvf test.tar.gz test/
|
||
test/
|
||
test/home/
|
||
test/home/sk/
|
||
test/home/sk/test/
|
||
test/home/sk/test/sample
|
||
|
||
类似的，我们可以用下面的命令来解压缩一个归档文件。
|
||
|
||
betty uncompress test.tar.gz
|
||
|
||
输出是这样的：
|
||
|
||
Betty: Running mkdir test && tar -zxvf test.tar.gz -C test
|
||
test/
|
||
test/home/
|
||
test/home/sk/
|
||
test/home/sk/test/
|
||
test/home/sk/test/sample
|
||
|
||
### 完整的Betty命令行列表 ###
