matching strings from 2 different files

[ng1]

I have 2 files. In some of the records, string 1 will match but other strings will not. I want to be able to report out the records from file 2 where string 1 matches string 1 from file 1.

Ex.

FILE 1
111
222
333
444
555

FILE 2
111 AAAA
345 DKDK
4445 45TG
444 BBB

In this example, I would want to report out line 1 and line 4 from file 2.

1111 AAAA
444 BBB

If you have UNIX, use the join command for this


In order to understand recursion, you must first understand recursion.

Yes, we are using Unix. I will check that command out. Thank you.

The join command did the trick. Thank you again taupirho! Here is the syntax that worked for me:
join -j1 1 FILE1 FILE2
