I need to check if I Filesystem exists, and if it does exist there is 300 MB of space in it.

What I have so far:

if [ "$(df -m /opt/IBM | grep -vE '^Filesystem' | awk '{print ($3)}')" < "300" ]
then
echo "not enough space in the target filesystem"
exit 1
fi

This throws an error. I don't really know what I'm doing in shell.

My highest priority is AIX but I'm trying to get it to work for HP and Sun too.

Please help.
