Replacing words
Hi, I have am using a file that contains names that I want to replace.

Basically file 1 looks like this

Code:
jack
joe
james
john

I have another file (file 2) that looks like this

Code:
jack      2345
joe       6848
james   3342
john     3432

Basically I want to replace column1 from file1 with column 2 from file 2 if its a match. The two files are of different length. Is there a fast way of doing this?
