Linux disk free space

All system admins will need to check, at some point, how much disk space is free on their systems. If the system is remote, or perhaps in a datacenter, you will need to run a shell command. the one you want is:

> du

This basic command outputs the space in terms of 1 kilobyte chunks, which isn't very readable. to get a nicely formatted output, run this:

> du -h

Nice and easy huh? Now why not script it and put it into a cron job??
