dusub: Subtract two 'du'-style listings [01333544084]
Life is a constant war against the limited size of backup media. Here
is my next weapon in the fight: dusub. Save a du listing
today, then find out tomorrow or next week what's been growing:
dusub olddu newdu
or
du … | dusub olddu
Positive numbers in the output represent an item that grew since olddu;
negative numbers represent a decrease in size since olddu.
Version 2 knows about "du -h"-style listings.
dusub is useful with sorttop:
du … | dusub olddu | sorttop
