Hey Cluber, thanks for this code.
My knowledge of awk is null, basically.
I ran it and got to this:
Code:
pgawk: script.awk:1: awk -F\; '
pgawk: script.awk:1:       ^ backslash not last character on line

I'm running this with Gawk for Windows (not at my laptop here).
Is that the reason why I'm getting this error?
If it is, I'll get a Linux VM running to test it out.

Thanks.

Mod Comment Use CODE tags for sample input and sample output; not just for code segments. Without the CODE tags, the spacing in the diagnostic messages from awk is lost.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
