    I'm trying to validate dump tapes.
    
    I liked someones idea of trying to restore the last file on the tape.
    
    The question was...how do I know which is the last file.

restore tv will print out things like

    dir		2	.
    dir		1536	./etc
    leaf	1630	./etc/dumpdates

A "dir" is obvious; a "leaf" is really just "not-dir".  A simple awk
script will then help you here:

    restore tv | awk '$1 == "leaf" {if (ino < $2) file = $3;} END {print file}'

This fails if that last filename has white space in it.
