sedを使って、区切りで改行してやると見やすい。

$ echo $PATH | sed -e 's/:/\n/g'

Before

$ echo $PATH
/home/ginpei/.nvm/v0.9.5/bin:/home/ginpei/.rvm/gems/ruby-2.0.0-p247/bin:/home/ginpei/.rvm/gems/ruby-2.0.0-p247@global/bin:/home/ginpei/.rvm/rubies/ruby-2.0.0-p247/bin:/home/ginpei/.rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

After

$ echo $PATH | sed -e 's/:/\n/g'
/home/ginpei/.nvm/v0.9.5/bin
/home/ginpei/.rvm/gems/ruby-2.0.0-p247/bin
/home/ginpei/.rvm/gems/ruby-2.0.0-p247@global/bin
/home/ginpei/.rvm/rubies/ruby-2.0.0-p247/bin
/home/ginpei/.rvm/bin
/usr/local/bin
/usr/bin
/bin
/usr/local/games
/usr/games

sedはファイル群を対象に置換処理するのにも使えて大変便利。
