> Description:
> I'm trying to parse di output of df command to check how much free
> space is left on my disks.
> I need to check this by a script.
> The problem is that, when the device name is long, we get a new line
> in the output (see example below).
> It's difficult then have data relate with the device name or mount
> poiunt usign grep and awk.
>
> Proposed Solution:
> simply add an option to not wrap the output text.
