I don't do memes as a rule, but this one's been doing the rounds on Planet Ubuntu, so I thought I'd give it a shot, too.

So, the results of the query are:

graham@bloodnok: ~$  history|awk '{a[$2]++ } END{for(i in a){print a[i] " "}}'|sort -rn|head93 bzr66 python2.446 sudo44 cd39 grep22 make19 ls18 vim11 tail11 lpvim

So now you know.
