Assuming $archive is your tarfile or tape device and $filename is the file you want you can just do...
$ tar tvf $archive
... for a file listing. Then to extract one file just do...
$ tar xvf $archive $filename
Add the 'z ' option as required if your archive 's compressed. Your other alternative would be to use dump/restore. Then do a...
$ restore -ivf
And you could 'cd ' down into the appropriate place, 'add ' the required files the 'extract '.
Will.
