Seriously, as shockneck already said using some non-standard shell (or non-standard tool in general) is always asking for trouble. Most of the times this asking goes unanswered but in the least convenient moment you will have to deal with some subtle intricacy on top of your already pending deadline.

I would rather learn an additional tool instead of taking that chance.

As a systems administrator i have seem many software developers using bash instead of ksh, nawk/gawk/whatever instead of awk, etc., etc.. Many times this ended at my desk asking questions like "why doesn't this script run correctly in my environment" or "why does this not work at the customers site, it is working for me".

This does not mean that these tools are bad at all. They are just a glimpse of a hint different in some way from their standard counterparts - maybe even better, but different. Chances are these differences will have an adverse effect once when you least expect it.

I hope this helps.

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
