'Scuse me, Guy (I've been landed on with both feet before by several users
when I asked a mild question about something you said earlier, so I am try-
ing to be cool about this) but why not 

find /file_system -inum inode_# -print [maybe -exec ls -l {} \;]

which would restrict the search for the inum to the file system on the device
in question?  That would be a bit quicker than searching all filesystems, as
a find on root would do.  A mount command would show what's mounted on what,
so you'd know which filesystem to search.

Sorry if I misunderstand.  Please readers if you answer don't just holler
'Guy knows his Unix' this time.  Maybe it's still slower than ncheck (I
haven't timed it yet).

thanks.
