Steve indubiately did not start from mine, although there was a great deal of interaction, joint evolution, discussion, etc. If you look it up, it says it took features from the original UNIX shell & from the PWB/UNIX shell, and thanks DMR & I for many discussions [Ken was off at UCB while much of this was going on.] I doubt that any actual code from the PWB shell was in Steve's. -- -john mashey DISCLAIMER: UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!mash, DDD: 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
