There's this meme going around:
deepak@vyomlinux:~$ history|awk '{a[$2]++ } END{for(i in a){print a[i] " " i}}'|sort -rn|head 1242 cd 565 vim 209 svn 128 rm 104 ant 97 grep 89 hg 87 ssh 77 cp 69 sudo deepak@vyomlinux:~$
Of course, these numbers are after ignoring duplicates and a few oft-used commands.
deepak@vyomlinux:~$ echo $HISTCONTROL ignoredups deepak@vyomlinux:~$ echo $HISTIGNORE &:ls:ll:new:s:[bf]g:exit deepak@vyomlinux:~$ alias ll s alias ll='ls -lrt' alias s='cd ..' deepak@vyomlinux:~$
