script name: nulls.awk

Code:
awk '
BEGIN { FS=OFS="|" }
NR2 == "" { NR2="0"}
1
' <inputfilename>  > <outputfilename>

these <inputfilename> & <outputfilename> should be passed while running the awk script in run time... input file may differs on every run.. so, usally for general scripts i use

ex: sh replace.sh
Code:
sed 's//0/g' $1 > $2

execution : sh replace.sh inputfilename outputfilename

this way i acheived.. but i failed to achieve same like

sh nulls.awk inputfilename outputfilename -- this is my desried one

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
