Put the lines from file A to end of lines in file B

Shell Programming and Scripting
1

I really can't figure this one out.

I have 2 files, one file is a list of hostnames and the other is a list of their corresponding IPs:

fileA:

example.com
another.org
thirdie.net

fileB:

1.1.1.1
2.2.2.2
3.3.3.3

I want to create a fileC that looks like:

example.com 1.1.1.1
another.org 2.2.2.2
thirdie.net 3.3.3.3

How would I achieve this? I have a huge sed command happening but I am not at work at the moment so I can't show you what I have so far. Any help would be great, thanks. fileA and fileB are generated from other scripts and will always have a matching amount of lines and corresponding to each other 1:1, so I just need to worry about putting A to the end of B

I believe this is what you are wanting to do:

$ paste file1 file2 > file3

$ cat file1 file2 file3
example.com
another.org
thirdie.net
1.1.1.1
2.2.2.2
3.3.3.3
example.com     1.1.1.1
another.org     2.2.2.2
thirdie.net     3.3.3.3

You're kidding... It's that simple.

Thanks for the help I will see how this goes
