So,

To keep up with the history meme hype that started last week on planet.gnome.org:

:~$ history|awk '{a[$2]++ } END{for(i in a){print a[i] " " i}}'|sort -rn|head -n 12 83 ls 73 cd 56 svn 35 sudo 19 screen 18 rm 18 cat 14 make 12 exit 9 kcmshell4 8 wget 8 dd

I'm affraid i'm using subversion more for deleting/moving than rm and mv...
