I use a number of command-line Unix utilities in ports for Windows or DOS, but usually have to read the instructions each time. And there's the rub; GNUish is a language that looks like English, but is a lot less intelligible. Please, does anyone know of any good books or online manuals/tutorials? I already have The AWK Programming Language by Aho, Kernighan and Weinberger, and the first edition of the Dale Docherty book on AWK and SED, but here I'm thinking of things like grep, csplit, cat, unique, paste, etc. The slight differences in syntax for how you enter /regexps/ into the shell - how you quote them, etc. - get frustrating.
Thanks...
