I have multiple directories on a BSD 4.2 system thhat is going away, so I need to dump my files and load them up on a VAX V/2.0. If I use the BSD tar(1), can that be read at the System V end? I suppose the alternative is a PD cpio, if someone has one, although I've never used it. This is a one-time requirement, so I'm going for simple.

If it is unfamiliar hardware the answer is still yes but use a small blocking factor when writing the tar tape ('tar cbf 5 ....' should do it.) The reason is there exist tape drives that cannot handle the 10240 blocks created by default by 4.2bsd tar (and have been reported on this list.) There is, however, no substitute for asking vendor if you could try a tape, perhaps at a nearby site using the proposed hardware. If you can 'tar t' it you should be able to read it back. -Barry Shein, Boston University
