Bash commands to combine files

Suppose that you want to combine two (or more) files, containing for example a series of data. There are, actually, two ways to do it in bash:

$ paste temp1 temp2 > temp
which adds the contents of the two files horizontally, like columns, and

$ cat temp1 temp2 > temp
which adds the contents vertically, one after the other.

Simple as that.
