This is an alias to shells to display mount output in formatted columns.

Add this alias to your rc shell(.bashrc, .zshrc, or whatever):

alias mountc='mount | column -t | sort -V'

Example output:

acataluddi

<?php

/**
 * Simple request response script
 *
 * Point you cURL request to this script to see all incoming data
 */

echo '*API*'. PHP_EOL;

{% endif %}

{# style 2 - short form #}
{% set tomcat_value = tomcat_1_value if (filepath == '/var/opt/tomcat_1') else tomcat_2_value %}

UPDATE: A better way! (August 2015)

As pointed out by @johntyree in the comments, using git reflog is easier and more reliable. Thanks for the suggestion!

 $ git reflog
1ed7510 HEAD@{1}: checkout: moving from develop to 1ed7510
3970d09 HEAD@{2}: checkout: moving from b-fix-build to develop
1ed7510 HEAD@{3}: commit: got everything working the way I want
70b3696 HEAD@{4}: commit: upgrade rails, do some refactoring
