Good luck!
I understood your point and changed the script as follows:

#! /usr/bin/nawk -f
first_file=$1
second_file=$2
BEGIN {
FS="@@"
}

FNR==NR {a[$1]; next}

!($1 in a)
' $first_file $second_file

But still i am getting errors as follows:
/usr/xpg4/bin/awk: file "/home/odyssey/f091018/cmp.awk": line 11: syntax error Context is:
>>> #nawk -F'@@' '
>>> FNR==NR {a[$1]; next}
>>>
>>> !($1 in a)
>>> ' <<<




Do i need to remove ' $first_file $second_file from the standalone script???
Please guide me ...
