I love qalc. It's not really a command, but a command line application. It's a calculator with floating point arithmetic, knowledge of units (even exchange rates if downloaded) and some solving ability. My top 10 commands is/are: 201 ssh 189 svn 90 sudo 84 rm 73 ps 70 qalc 66 mplayer 60 scp 47 less 46 cp Interestingly, if I remove the ls and cd removal, ls comes in at only the fourth spot. (cd comes at the no. 1 spot, unsurprisingly.) P.S. I had to change the $2 in the awk command to $4, since I store dates with the commands.
