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 !

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
