I have a file /T, where the text of that file is:

1
2
3
4
5
6

I wish to change that to a two-column format

column </T --(output set to new document) gets:
1 2 3 4 5 6
which probably makes sense as I have no option and no argument.

column -c <T (output set to new document) yields nothing, which makes sense because I haven't specified an argument

column -c 2 </T -- (output set to new document) I expect

1 2
3 4
5 6

BUT get

1
2
3
4
5
6

It would seem I'm specifying the argument incorrectly. If that's true, what is the proper syntax?

And, if I can get past the above problem, what's the story with an -x option; it doesn't appear in the "man column" I've looked at, but elsewhere I've seen it stated that (with that option) I should get:

1 4
2 5
3 6

help? TIA
