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 whoamisk
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,***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] whoamiGets your system username.[2] finger $(whoami) | sed 's/.*: *//;q'Gets your full name.1Betty: Running whoamisk
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 testtest/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。
