Tools: April 2008 Archives

What commands do you run?

| | Comments (2)

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 "%5d\t%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`

svn diff -x -w $* | view -
and ssq is just an alias for svn status -q.
