You should use [code]code-tags[/code]

Could you please tell us what you've tried out so far? as you know we don't do your homework for you.

Here's a quick n dirty possible soln, just for fun
(in fact I knocked it up as a one liner, but its tricky to read)
Code:
for str in `cat t1.t|awk '{print $1}'`
do 
    grep $str t2.t>/dev/null 
    if [[ $? -ne 0 ]]
    then
        echo $str
    fi
done
Definitely not the best soln and it depends on exactly what you want to see as results.

Anyway, here's some good links
