I suggest "sed & awk" by Dale Dougherty, issued by O'Reilly and Associates. It is simply the best book on the subject i ever read.

No, you don't. You can write multiline awk programs as part of the normal shell code as long as you enclose it in single quotes. Note the single quotes at the beginning and the end of the awk-program:

Code:
some_command |\
awk '{
        /^#/ {
                  next
             }

        /^\/\// {
                  next
             }
     }' /path/to/file |\
other_command

I hope this helps.

A Google search for awk tutorial beginner OR novice produces about 70K hits. The first 2 looked good to me; I wrote and delivered a begiinning awk sub-course as part of a basic *nix series.

I agree with bakunin about the sed & awk book. See also:
