MySQL "awk" doubt- do reply

Hi

I am new to this shell scripting.
how to get the line by line fields in a for loop.

for eg(my script):

line=0
for s in `cat system`
do
line=`expr $line + 1`
a=`awk -F' ' 'NR=$line{print $7}' sample`
done

this is my script where I get a syntax error.
my error: is Field $() is not correct.
The input line number is 1. The file is samp.
The source line number is 1.

can anyone help me.

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
