You can run dumpfs, eg line=`dumpfs 2> /dev/null $1 | head | grep superblock\ location` eval `echo $line | sed -nEe 's/superblock location.*id.*\[ (.*) (.*)\ ]/printf %0x $((0x\1 << 32 | 0x\2))/p'` I use this in a script to determine the ID so I can modify fstab after the install has finished. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
