I'm trying to use du to sort the output by filesize, but it doesn't looks like there's an option for that.

Can I pipe it into another command to handle the sorting?

Shorter, and more succinct (and no Perl ;) ):

du -sm | sort -nr

    Gnu sort has an option -h to sort human-readable SI numbers, with 4K being smaller than 1M. It's an option when -m/-g/-k don't work well. – Daniel Beck Nov 28 '12 at 19:57
  • Nice, +1, you don't need the * though, du will run on the current directory by default. – terdon Nov 29 '12 at 13:26

Try this:

alias duf='du -sk * | sort -n | perl -ne '\''($s,$f)=split(m{\t});for (qw(K M G)) {if($s<1024) {printf("%.1f",$s);print "$_\t$f"; last};$s=$s/1024}'\'
