combine files line by line
Hi all,

I once knew of a simple unix command to do this, but I can't remember it and I can't find it by searching.

I have two files.

### FILE A ####
A1
A2
A3
A4
A5

### FILE B ####
B1
B2
B3
B4
B5


I would like the output file

### OUTPUT ####
A1 B1
A2 B2
A3 B3
A4 B4
A5 B5

Do any of you know it? Thanks a million.

Ha, I just tried seaching again, but I used the title of this post as the search term in google and found it. Smilie

It's "paste"

I'd tried various combination "lateral join files" etc before.
