[Moved to general@ because I think this'll be fun.]

Oh, easy:

$ perl -lane'if($F[0]eq q/sudo/){shift at F};$h{$F[0]}++}{map{printf"%3d\t%s\n",$h{$_},$_}sort{$h{$b}<=>$h{$a}}keys%h' .bash_history
[...]
 55     perl
 21     vi
 21     rm
 15     cd	(*)
 13     less
 12     xlock	(!)
 10     diff
  9     cat
  9     chmod
  9     wordnet	(^)
  8     ssh
  7     apt-get
  7     perldoc
  6     touch

cd isn't relevant, xlock isn't a command-line application, and
wordnet isn't typical usage.  Neither is perl in this case, but it
*is* my favourite.

So we're left with vi, rm, less, diff, cat, chmod, ssh, apt-get,
perldoc and touch.

Others that didn't make it in:  netcat (absolutely *essential*
sometimes), screen (I've never seen a good Unix sysad who didn't use
it), cvs and rcs, gpg, emacs (does that count as command-line?  I
think vi does), oh, and patch.  fmt is great, par is better.  Sleep
is useful for stuff like this:

	$ sleep $[ 4 * 60 ] && echo ^G # boil an egg

Sudo rocks, as do dump and restore, and rsync.

Hmm, I think those are my favourites.  Combinations work well:  the
most egregious example I can think of is using diff to create a
patch which I hacked into a perl script to apply over and over to
different files, found with find.

jason, of course, perl can imitate maybe half of those utilities
