 Does the --portabililty option not do what you need?


I experimented a little with it, but I failed to find a format suitable for my needs... what I needed was something simple to slice with cut, and even with -P I got

address@hidden ~]# df -P
Filesystem         1024-blocks      Used Available Capacity Mounted on
/dev/mapper/VolGroup00-LogVol00  67763800  43385020  20936504      68% /
/dev/sda1               101086     26555     69312      28% /boot

while with -q I get:

68% /
28% /boot

OK - you didn't mention -P, which is the solution to the line-folding issue. For picking out specific fields, I'd be tempted to use cut or awk rather than introduce a new option.
