Packed with a whopping 81 UNIX commands, here's the complete set of man pages for UNIX v5... http://www.tuhs.org/Archive/Distributions/Research/Dennis_v5/v5man.pdf Worth having a look: chmod (page 39) - Yeah, octal modes are a pain!... dc (page 49) - What, no bc?... Nah, learn RPN, ya wimp! diff (page 52) - "Jackpot!"?... Yup, I've seen it for myself. goto (page 67) - Now you know the origin of the ':' command. if (page 69) - Primitive flow control, pre-csh/Bourne shells. shift (page 104) - Example of a shell script using the above. tee (page 113) - "pipe fitting",... Yup, very descriptive. Ah, the good ol' days... Gilbert -- Manitoba UNIX User Group E-mail: <gedetil@muug.ca> c/o Gilbert E.
