Discussion on: What are your five most used terminal commands?

    $ history|awk '{print $2}'|sort|uniq -c|sort -rn|head -5
       176 git
        86 ack
        70 exit
        34 prove
        29 vi

exit will be because I'm constantly creating and destroying virtual terminals in GNU screen. ack is like grep but better. prove runs my tests. vi is so far down the list because most of my work is in a single vim that has been running for [looks at process table] three months now.
