Top Ten UNIX Shell Commands

Current trend is to run the following one-liner from IBM. I’m usually logged in to the following three systems, with very different results.

vmlinux.org

$ history |awk '{print $2}'|sort|uniq -c|sort -nr|head -10
144 ls
 61 cd
 58 sudo
 29 less
 23 emacs
 19 bzr
 16 vim
 11 rm
 10 wget
 10 mv

My personal life. Not much different from my professional dito. Most visible difference maybe is my use of bzr instead of svn. At the time we decided on svn at work bzr had not matured enough and darcs didn’t (still doesn’t) have a Windows client as good as TortoiseSVN.

Build server @work

$ history |awk '{print $2}'|sort|uniq -c|sort -nr|head -10
108 cd
 63 svn
 44 search
 41 ls
 25 sudo
 23 less
 23 ./build.sh
 21 make
 17 ./netprobe
 16 man

Mostly work stuff, ‘search’ is a small wrapper around find that skips .svn dirs and semantic.cache files and other annoying things you constantly run in to when looking for something. The build script is a small wrapper around make for our Snapgear and uClinux-dist trees. Netprobe was one of the last prototypes I wrote to investigate some UNIX peculiarities involving libnet and libpcap.

troglobit (my laptop)

$ history |awk '{print $2}'|sort|uniq -c|sort -nr|head -10
140 sudo
 47 ifconfig
 45 less
 27 ps
 26 ssh
 25 iwconfig
 21 ping
 21 man
 15 ls
 15 cd

Well, I’m having trouble with my laptop network. The wlan (wpa_supplicant) doesn’t like suspend/resume on my ThinkPad T43.

Update: I had to make an update to this, even at first I had my doubts about the first script. It didn’t feel right, now after revising it, and reading Planet Debian, I noticed Erich Schuberts entry. There it was, the working script, which I only had to bashify! Thanks Erich!
