从命令行将文本行拆分为单独的行

Question

根据字符或模式将单个文本行拆分成单独的选项有哪些？我想从命令行执行此操作。

例如，当您要检查 PATH 时。通过一个简单的命令，我想拆分如下内容：

    /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

/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

Answer 1

类似

sed s/:/\n/g yourinput

应该可以解决问题

Answer 2

使用 tr 实际上更容易，如示例所示this 问题。这是命令

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