Question

The output of the "df" command in Linux may show long volume names that cause the remainder of the line to wrap to a second line.

How can I correctly process wrapped output in Monitor Solution for Linux?

[root]# df -h

What Monitor Solution needs, is to have the "df" command return the results in this format:

Filesystem            Size  Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00                      4.8G  572M  4.0G  13% /

Answer
We recommend using one of the following commands to get the unwrapped output from the "df" command:

df –hP

df –hP | column –t

[root]# df -hP
