Whatever it technically may be, the POSIX spec calls it a file system name, so I'm using that term to be consistent with it. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/df.html#tag_20_33_10 > You need to look at the 2nd line and you may use the '%' sign to synchronize > fields and you may even do this: > > /usr/xpg4/bin/df -P /etc/passwd /etc/hosts > Dateisystem 512-Blöcke Belegt Verfügbar Kapazität Eingehängt > auf > /dev/dsk/c1t0d0s3 24203960 23115442 846480 97% / > /dev/dsk/c1t0d0s3 24203960 23115442 846480 97% / > > and just compare the last two lines. What if this is done while something else is writing to a file? As far as I can tell, there's nothing to say the number of free blocks can't change between printing the first and second lines. As for the '%' sign method, see Geoff's message and my reply to it. - M.
