I usually don't do memes, since I don't really like them. But these one I just saw at Living Code is different... it's kind of geek. So here it goes, here is my list:

$ history|awk '{a[$2]++} END{for(i in a){printf "%5d\t%s\n",a[i],i}}'|sort -rn|head
   72	ls
   61	./ika****.py
   60	cd
   56	svn
   41	./dumpfirefoxcookie.py
   26	cat
   20	./showmap.py
   18	./maximizeworkers.py
   17	./ika****_distributewine.py
   16	./ika****_showmap.py

I had to ofuscate some of them to avoid getting in trouble for this... LOL
