Re: help with awk

[Jason Bowen <jbowen%infinitecactus.com@localhost>]

Anything not in a BEGIN{} or END{} block will be applied to each line of 
the input.

It also seems like you're getting a bit mixed up with shell vs awk 
variables. With awk, $i is field i of the input. If you want to use the 
value of a variable named i, like in your loop, then just write i 
without a dollar sign.

Also, in your for loop you're already grabbing individual fields, so 
there's no need to split the line: $i will be the ith field of the input 
line.

Does

    BEGIN { print "# $NetBSD$"; }
    /(^|\n)source =/ {
        for (i = 1; i <= NF; i++) {
           sub("\"","")
           sub(",","")
           if ($i ~ /^https/)
              name=$i
           if ($i ~ /[a-f0-9]{40}/)
              vers=$i
        }
    }
    END { print "DISTFILES+=\t" name "-" vers ".tar.gz" }

do what you want for DISTFILES and give you enough to go on for SITES.?
