A friend of mine told me that on techie blogs there is a new meme going on: show off the most used commands, starting from shell history:

history | \
 awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | \
 sort -rn| head -15

I've got 20 times the default bash history size (10k lines), so it'll yield interesting results. I also use the history timestamp feature, so a little sed strip timestamps out.

Let's see:

 13:19:50 vjt@voyager:~/code$ history | 
     sed 's#^[ 0-9\[\/\:]*\]\([^ ]*\).*#\1#' |  
     awk '{a[$1]++}END{for(i in a){print a[i] " " i}}' | 
     sort -rn | head -15
928 l
577 ssh
389 ping
381 cd
300 dig
259 telnet
153 sudo
126 ifconfig
125 whois
113 ps
96 svn
91 cat
73 fg
68 vi
61 ..

yeah, I do a *LOT* of ls, l is actually ls -alFGs (I'm on Darwin). This list exposes my recent habits, because I'm coding less and managing more (no gcc, no irb, lots of dig & whois). svn is still there, of course . ssh means that these results should be aggregated with other histories coming from the other boxes I log on to.. but that's a topic for anoter post .

Which are your results?

Post them here!

UPDATE 2008-06-03

As my recent habits are more coding than writing docs, I re-ran the history analysis.. and these are the new results:

1796 l
981 svn
705 ssh
693 cd
666 ping
402 vi
356 ifconfig
352 telnet
321 dig
315 sudo
283 fg
240 grep
188 ..
183 cat
157 ps

heh. nifty. .
