I suspect it would.

Reformatting for readability:

BEGIN { f = "" }

{
        if (f != $1) {
>>>>            cmd = "grep -E \"" $1 "\" fn.txt" | getline var
                close(cmd)
                system("echo " $1 " >> desc.txt; grep -A 100 \"Description:\" 
'\''" var "/control'\'' >> desc.txt; echo >> desc.txt;")
                f = $1
        }
}

Please try changing the marked line to:

                cmd = "grep -E \"" $1 "\" fn.txt"
                cmd | getline var

I think that will make a difference.

Thanks,
