Know a better way?

If you can do better, submit your command here.

What others think

Doesn't quite for the same on my systems. Try it this way as a test:

df -P | awk ' NR>1 (S=$5) (M=$6) { print "Your Systems "M" is """S" Full" } '

The -P option makes df use the POSIX output format, which makes it a lot more "greppable". If the output looks like what you want, simply integrate this version of the command into the above example.

i.e try it this way:

HDD=$(df -P | awk ' NR>1 (S=$5) (M=$6) { if (S>90) print "Your Systems "M" is """S" Full" } ') ; [[ $HDD ]] && echo "$HDD" | mail -s "Hard-Drives Full" TO@EMAIL.com -- -f FROM@EMAIL.com >/dev/null

Tested ok on RHEL 5 and Fedora 11.
