I like this concept but I am a bit slow in Byte arithmetic...
df -h (human readable-had me in mind)
du -sh /home/* give me summary of each folder (again human readable)
du -sh /root/* you get the idea
OH and one for the road...the script that I wrote (with PLUG help) for
checking user profiles and emailing users with large profiles (can be
adapted pretty easily)...
# cat chksize-users-profiles
#!/bin/sh
wfile1=/root/scripts/users-homes
wfile2=/root/scripts/profiles-exceed-limits
chdirect=/home/filesystems/samba/profiles
size_plateau=153600
du -s $chdirect/* > $wdirect/users-homes
> $wfile2
for i in `cut -f1 $wfile1`; do if [ $i -gt $size_plateau ]; then grep $i
$wfile1 >> $wfile2; fi; done
for i in `cut -f2 $wfile2`; do echo "Your Profile is getting too large.
You probably need to clean up your email or move some of your files in
your My Documents folder. You might want to check out
http://www.mullenpr.com/support/profiles.html for suggestions on how to
reduce the size of your stored profile." | mail ${i##/*/} -s "You are
close to reaching your quota for file space on the server"; done
