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.
Good to know!
You can also splice data when using “newline” as delimiter:
$ cat file1
1 2
3 4
$ cat file2
a b
c d
$ paste –delimiter=”\n” file1 file2 > file3
$ cat file3
1 2
a b
3 4
c d
Interesting. Thanks for sharing that!
