Tutorial created using: Red Hat Enterprise Linux ES release 4

File system disk space usage can be determined using the "df" command. Information about df can be obtained via "man df" or "df --help". The "-h" switch can make the results a little easier to read. Below, we'll execute "df -h" to display the disk space usage of the file systems in human-readable form.

df -h
disk space usage reported by df

Notice in the results that df reports on the amount of space used and the amount of space available on the file systems.
