Three Monkeys, Three Typewriters, Two Days: Me N for N

Me N for N > 3

To go with this whole awk meme:

% history | awk '{a[$3]++ } END{for(i in a){print a[i] " " i}}' | sort -rn | head
37 latex
27 bibtex
13 cvs
4 ls
3 history
3 backupwork
2 xterm
2 emacs
2 clfiles
1 xdvi

Some notes:

Have to adjust the awk because tcsh history has slightly different fields
The fact that tcsh has history per-shell by default means that this is only capturing that one xterm. I have 16 others open right now
I've clearly been working on my thesis

You get better formatted columns with uniq. :-)

history | awk '{print $3}' | uniq -c | sort -nr | head

You need anpther sort in there:

history | awk '{print $3}' | sort | uniq -c | sort -nr | head

to make sure all the commands get lumped into their own group.
