[Hampshire] Top ten commands in history

I've seen this on IRC before but have not seen it mentioned on the mailing list. It's just a bit of fun
to find out what the most common commands are in your history. Neil takes credit for actually writing
it, I just run it on boxes when bored :)

On my Ubuntu desktop:-

alan@wopr:~$  history | awk '{print $2}' | sort | uniq -c | sort -rg | head -n 10
    105 cd
     88 ls
     64 sudo
     29 ssh
     14 cat
     14 apt-cache
     10 ./configure
      9 wget
      9 ping
      7 history

on one of my Debian servers:-

alan@bishop:~$  history | awk '{print $2}' | sort | uniq -c | sort -rg | head -n 10
    129 sudo
     89 cd
     73 ls
     67 screen
     15 vi
     15 grep
     10 top
     10 date
      9 ping
      7 tail

So, what are your top ten commands in the history? What can we learn from this? :)

Cheers,
Al.
