sorry, i deleted a recent email where someone was looking for a good
intro to shell programming (emphasis: programming, not usage).
my thoughts: first, one book that was mentioned was by ellie
quigley. i remember a book by her on perl. awful, awful book.
loaded with errors. personally, i wouldn't go near anything by her
unless she's improved dramatically over the years.
second: for maximum portability, consider sticking to strict POSIX
constructs. yes, bash has lots of cool features. too many, in fact.
if you're having to push the bounds of simple POSIX programming, you
should probably be looking at another language. again, that's a
personal opinion, but it's just too much of a pain to try to remember
whether a particular shell language construct was bourne, korn, bash
or some intersection thereof.
third: good shell programming books? frankly, i haven't found any.
and i'm still looking for one to use as a student text in a shell
programming class. so far, i use my own manual and include the POSIX
standards as a printed supplement. but i'd still like to find a
decent book, ideally POSIX-oriented.
