How to join or combine 2 files by column ?

[Sammy_2]

# ==> cat test1
John
pat
george

# ==> cat test2
kerry
edwards
bush

How do I join/combine 2 files so it looks like this:
# cat test3
John Kerry
Pat Edwards
George Bush


Thanks

Please ignore the lower/upper case in last file (test3). I am just trying to combine 2 files.

paste test1 test2 > test3

Man paste for details.

# paste file1 file2 > file3

[Sandman!]

# paste -d " " file1 file2

...to separate the merged cols with a space instead of the default character. See the manpage of paste(1) for details.

Thanks paste command works great.
