Please avoid useless use of cat and also useless use of awk.

Always use shell builtins where ever possible because it will help significantly improve the performance of your script.

Assuming you have one record for each key and it is sorted:
Code:
#!/bin/bash

i=100
while IFS="," read v1 v2 v3 v4 v5 v6 v7
do
        if [ $i -eq $v1 ]
        then
                # Action here
        fi

        (( i++ ))
done < sites.txt

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
