Apparently, there's a shell history thread making its way around the tech blogs and Dr. Bacchus put in his two cents. So in the spirit of "if you don't even really care about trying to beat them, you might as well join them," I submit mine from my web server:

[llang@jwsinteractive1 ~]# history | awk '{print $2}' | sort | uniq -c | sort -rn | head
274 ls
126 cd
104 vim
40 rm
32 cp
26 mv
20 mkdir
20 locate
19 ftp
19 exit

Being a remote server for a fledgling web business, I've spent a lot of time getting files into the right places and editing config files and code. Not to mention the time spent just looking for the right thing to edit.
