[brlug-general] df breaks scripts

[Dustin Puryear]

I've had problems with this in the past, and it's causing problems 
again. Sigh. df on Linux simply insists on wrapping text, and this 
breaks things.

For example, take a look at this:

$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                        8030648   4390580   3225556  58% /
/dev/hda1               101086     10839     85028  12% /boot
tmpfs                  1037880         0   1037880   0% /dev/shm
/dev/mapper/VolGroup00-LogVol02
                      141282016  64718168  69271332  49% /scratch
/dev/mapper/VolGroup01-BackupPC
                      196013428 142346300  43710164  77% /home/backuppc/data


This breaks a million scripts out there.

Yes, we can use -P to fix this, but how many scripts are out there that 
assume that.. oh, call me crazy.. that just a simple 'df' prints out 
output that can be properly awked?

Anyone been bitten by this?
