Intelligently merge two files
I have two files as the following:

file1:
Code:
243
242
243
242
242

file2:
Code:
243          car       360    396k
242          bike       240    217k

I want the corresponding $3 in file 2 added as $2 in file 2.

The expected output would be:
Code:
243 360
242 240
243 360
242 240
242 240

I figured that I can do this through two loops, but I am not sure how to extract the exact values that I would need, here is that I was thinking of:
Code:
 while read y; do
                while read z; do

                done<file1
        done<file2

Is there a better way to do this using only awk or sed?

Thanks.

I think I figured out a bash based method. I can find matches now. Figuring out a way to print should be straight forward.

Code:
while read y; do
                while read z; do
                        a=$(echo $y | awk '{print $1}')
                        if [ "$a" = "$z" ]; then
                                echo $y
                        else
                                echo nomatch
                        fi
                done<file1
        done<file2
