A quick script that can be triggered to email administrators (ie: using nagios) the largest subdirectories from a parent directory. Can also simply print the results to STDOUT.

Doesn’t work with the Solaris versions of `du’ and `sort’. :(

#!/bin/sh

TOP=20

DIR=/home/*

ADMIN=admin@host.com

if [ $1 == "-p" ]

then

        du -sc $DIR|sort -rg|grep -v total|head -n $TOP

        exit

fi
mail -s "**Space Utilization Report for `hostname`**" $ADMIN
