I ran across The Shell Meme on Lincoln Stoll’s blog, and figured I’d, uh, borrow it.

Run this command in a new shell:

history | awk '{ a[$2]++ } END { for(i in a){printf "%5d\t%s\n ",a[i],i} }' | \
  sort -rn | head

I get this as the output

379    git
221    cd
181    ssh
77    sudo
69    ruby
66    ls
34    rake
33    m
32    bb
31    m.

bb changes directory straight into my BrightBox source directory. m and m. are TextMate alias’s to open files or directories in TextMate for editing.
