Top Forums Shell Programming and Scripting how to get one particular section (using awk)? Post 302467441 by DGPickett on Friday 29th of October 2010 11:17:23 AM

Well, UNIX optarg can be confusing, especially when awk has multi-letter commands in non sh style mixed in. Probably equivalent to "-v RS=...". I am not an optarg fan, as it makes things confusing to save a key stroke or two: training and mistakes are more expensive. For instance, "-abcde" might mean "-a 'bcde'" or "-a -b 'cde'" OR . . . "-a -b -c -d -e" depending on which if any one letter option takes an argument.

https://www.unix.com/man-page/All/3/optarg/

Looks like xpg4 awk or nawk (new awk) or the wrong O/S man page:

Man Page for awk (OpenSolaris Section 1) - The UNIX and Linux Forums
Code:

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
