True, but what columns is your awk going after?  The problem is that 'df' 
output isn't standard.  You get different output on AIX than Linux and 
*BSD, not sure about Solaris or HPUX.  So that's what POSIX is for. :)

Yes i've been bitten by this before... my solution was to add -P to all 
the broken scripts haha.  I do agree that the multi-line df output caused 
by the default RedHat LVM is quite aggravating.

I've run into similar problems with vmstat/iostat output being different 
between Linux kernels and other Unices.  Unfortunately i haven't found a 
-P flag for vmstat.
