What commands do you run?
People have been posting in their blogs about what command they run, based on their shell histories. The command that I've seen looks like this:
history|awk '{a[$2]++} END{for(i in a){ printf "%5dt%s n",a[i],i}}'|sort -rn|head
That works, of course, but who wants to use awk and the shell? I pulled out the old Data::Hash::Totals module I wrote a while back, along with Perl's built-in awk simulation:
$ history | perl -MData::Hash::Totals -ane'$x{$F[1]}++;' -e'END{print as_table(%x, comma => 1)}' | head 207 vim 143 svn 125 make 90 ack 77 cd 45 sdvx 34 ssq 31 ls 25 ./login-fixup 19 tail alester:~ : cat `which sdvx` #!/bin/sh svn diff -x -w $* | view -and ssq is just an alias for svn status -q.
