Display the history and optionally grep

2010-05-19 153 words 1 min read

Ever wondered how good it would be to have a command/function that would display the history or display the history with <a class="zem_slink" title="Grep" rel="wikipedia" href="http://en.wikipedia.org/wiki/Grep">grep.

Would be really good right, well someone thought about this πŸ™‚

$ h() { if [ -z &#8221;$1&#8221; ]; then history; else history | grep &#8221;$@&#8221;; fi; }

Place this in your .bash_profile and you can use it two different ways. If you issue &#8217;h&#8217; on its own, then it acts like the history command. If you issue:

h cd

Then it will display all the history with the word &#8217;cd&#8217;
