Shell should take input from the user instead of assuming it to be "4"

I have replaced the prints with echos and indented for reading purposes. YOu had an if construct which I assume you put in for debugging purposes.

I should have quoted that I am working in KORN shell. I don't know how much implications it has on the syntax, but here is the O/P of your amended script.

Code:

3
-n 1
-n 2
-n 3

-n 1
-n 2

-n 1

Plz advise !

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
