1. History of tar, cpio, pax, dump?
What is the history of those elementary backup tools tar(1), cpio(1),
I've vaguely associated tar with BSD and cpio with System V, but I've
really come too late into the Unix world to still have experienced this
dichotomy first hand. Looking at the V7 manual pages that are floating
around on the web, I've found an entry for tar(1) there but none for
cpio(1). I understand that the name "tar" is derived from "tape
archiver", and "cpio" from "copy in-out".
Regarding pax(1), I seem to recall that this is an invention of the
POSIX committee. Supposedly, they couldn't agree whether to standardize
tar or cpio so a new utility was created. There is no obvious derivation
for the name "pax"--other than the Latin word for "peace", hmm.
The man page of BSD dump(8) states that "a dump command appeared in
Version 6 AT&T UNIX". Interestingly, this implies that dump preceeded
FFS. Again, I always thought dump to be BSDish, but then my experience
with actual pre-SVR4 System V systems is minimal. The V7 man pages don't
Any historical facts/trivia appreciated.
