I tried the script with ur sample input, and it was working. Its not working means is giving any syntax error or its giving wrong result. And the heading is not printed in the script u can add BEGIN in the awk script and print the heading.

Try this....

As you have not specified the record delimiter, I assuming it as comma (,).

awk -F, 'NR==FNR {a[$1]=$2} NR!=FNR {if(a[$1]=="") {next} print $1,$2,a[$1] }' T2 T1

You will get the expected output.
