Text 将文本行从命令行拆分为单独的行

有哪些简单的选项可以根据字符或图案将单个文本行拆分为单独的文本行？我想从命令行执行此操作

例如，当您想要检查路径时。通过一个简单的命令，我可以拆分如下内容：

    /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

进入更具可读性的领域

/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

差不多

sed s/:/\\n/g yourinput

使用tr应该做这个把戏实际上更容易，如问题中所示。这是命令

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

这是什么操作系统/命令语言？你需要在某处指出这一点。
