Question

根据字符或模式将单个文本行拆分为多个简单选项有哪些？我想从命令行执行此操作。

一个例子就是你想要检查PATH。只需一个简单的命令，我就可以分开：

    /Users/jeff/.rvm/gems/ruby-2.2.1/bin:/Users/jeff/.rvm/gems/ruby-2.2.1@global/bin:/Users/jeff/.rvm/rubies/ruby-2.2.1/bin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/texbin:/Users/jeff/bin:/Users/jeff/Utveckling/Alan/alan/bin:/Users/jeff/.gem/ruby/1.8/bin:/Users/jeff/.rvm/bin

/Users/jeff/.rvm/gems/ruby-2.2.1/bin

像

这样的东西

sed s/:/\\n/g yourinput

使用 tr 实际上更容易，例如在this问题。这是命令

echo $PATH | tr ':' '\n'

将文本行拆分为命令行
