Does anyone know if there has ever been an attempt to create a unix system that knows how to handle multiple file generations a' la TOPS-20 and VMS? I realize the inherent problems to such a scheme but someone might have at least contemplated doing it. Thanks, Chris Warth ..!inhp4!ulysses!csw ATT Bell Laboratories Murray Hill NJ

Sunny, Sorry I took so long in replying... Some user-contributed software distributed with BSD2.9, called newcsh by Ken Greer from HP-Labs does exactly what you describe. Plus, it has an optional time-out feature for automatic logout after selected idle time, terminal mode sanity checking, and history saving between logouts. It requires only minor changes to the csh source (it affects only a half dozen or so of all of the csh code files), and is otherwise transparent. No filters; it's part of csh. It even flashes the screen if it can't complete your command. We've been using it for a month or so (on bsd4.1); Ken Greer says they've installed it as their standard csh there. I think it's great!

We have a shell called tcsh on out pyramid (vers 2.3 of OS/X) It seems to be the version as distributed on the 2.9 tape, i.e. ^D and ESC command recognition and completion, autologout and automatic history update over multiple logons. Whose version of tcsh is this. Its really not too bad. -- Mike Meyer -- Phone (608) 263-7310 EASY ARPA: mikem@uwisc.arpa CORRECT ARPA: mikem%wisc-stat.uwisc@uwisc.ARPA UUCP: ...!{allegra,heurikon,ihnp4,seismo,sfwin,ucbvax,uwm-evax}!uwvax!mikem
