split header row into one column
So, I have a massive file with thousands of columns

I want a list of the headers in one column in another file.

So I need to strip off the top line (can use head-1)

But how can I convert from this format:
A B C D E F G

to

A
B
C
D
E
F
G


Thanks in advance Smilie
