Betty:和你的Linux说说话

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

Betty工具有一些命令格式。如果你输入“what is my user name”而不是“whats my username”,它是不能识别的。所以,你只能输入Betty支持的英语短语。

下面给出一个Betty支持的完整的命令行列表。
