dumpdir - print the names of files on a dump tape
dumpdir [ f filename ]
Dumpdir is used to read magtapes dumped with the dump command and list the names and inode numbers of all the files and directories on the tape.
The f option causes filename as the name of the tape instead of the default.
default tape unit varies with installation
If the dump extends over more than one tape, it may ask you to change tapes. Reply with a new-line when the next tape has been mounted.
There is redundant information on the tape that could be used in case of tape reading problems. Unfortunately, dumpdir doesn't use it.
