PATH環境変数をより人間が読める方法で表示したい。
$ echo $PATH
/Users/arturo/.rvm/gems/ruby-1.9.3-p392/bin:/Users/arturo/.rvm/gems/ruby-1.9.3-p392@global/bin:/Users/arturo/.rvm/rubies/ruby-1.9.3-p392/bin:/Users/arturo/.rvm/bin:/usr/local/git/bin:/Users/arturo/.gvm/groovy/current/bin:/Users/arturo/.gvm/grails/current/bin:/Users/arturo/.gvm/griffon/current/bin:/Users/arturo/.gvm/gradle/current/bin:/Users/arturo/.gvm/lazybones/current/bin:/Users/arturo/.gvm/vertx/current/bin:/Users/arturo/.gvm/bin:/Users/arturo/.gvm/ext:/usr/local/git/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin
私はこのようなことを考えています:
$ echo $PATH | some cut and awk magic
/Users/arturo/.rvm/gems/ruby-1.9.3-p392/bin
/Users/arturo/.rvm/gems/ruby-1.9.3-p392@global/bin
/Users/arturo/.rvm/rubies/ruby-1.9.3-p392/bin
/Users/arturo/.rvm/bin
