I have a tape from a Berkeley system (4.2) written in tar format. I would like to read it into a System V Unix. Of course tar has been "fixed" so the two tars are incompatable. So, Does anyone have a tar program written for System V Unix which can read berkeley tar tapes? Please send me mail if you do. I could use it! (UNIX is a TM of Bell Laboratories as we all know). Thank you!

I seem to remember that this facility is broken in System V, so I am at a loss to understand how one can extract an arbitrary tar tape on System V. Oh, I know! Maybe if you wait 'till the next release. (tounge firmly in cheek) -Mike "186,000 miles per second - Not just a good idea, it's the LAW!"

Oh great. Now we have Berkeley tar tapes and everybody-else tar tapes. The BSD sites are bringing on their own isolation from the rest of the UNIX community.

Well, I'm not yet sure Berkeley's 4.2BSD "tar" is incompatible. Berkeley
writes "tar" tape entries for directories, as well as files ("tar" should
have done that in the first place), but those entries merely cause "tar"s
not equipped to handle them to complain about being unable to create
"./src/foobar/include/" and continue reading in the non-directory entries.
The "-o" option in the Berkeley "tar" causes those entries not to be written.
I've sent "tar" files from 4.2BSD systems to System III systems (not tapes,
admittedly - the "straight" System III systems we have are little boxes with
no 9-track tape) and read them with no problem. Let's not cry wolf.
