you can grab the columns using:
awk '{ print $1, $2 }' file_nm > file_nm_out
and combine ( up to 12 -- but some characters might get swallowed up )
the 2-column-output-files with paste:
paste file1 file2 > file_comb.1
However, with lots of files... this will become a little bit of a challenge.
I'm willing to bet there's an easier approach to your actual problem.
meaning -- why do the first 2 columns need to appear in a new file?
and how many files are we actually talking about?
what is the final destination for this data file we're building?
how were the initial files created in the first place?
it seems if we redesign any one of these steps, we might be able to design a better end-to-end process.
Perhaps you could restate the actual issue?

NAME
jpegexiforient - reads or writes the Exif Orientation Tag
SYNOPSIS
jpegexiforient [switches] jpegfile
DESCRIPTION
This is a utility program to get and set the Exif Orientation Tag. It can be used together with jpegtran in scripts for automatic orienta-
tion correction of digital camera pictures.
The Exif orientation value gives the orientation of the camera relative to the scene when the image was captured. The relation of the '0th
row' and '0th column' to visual position is shown as below.
Value | 0th Row | 0th Column
------+-------------+-----------
1 | top | left side
2 | top | right side
3 | bottom | right side
4 | bottom | left side
5 | left side | top
6 | right side | top
7 | right side | bottom
8 | left side | bottom
For convenience, here is what the letter F would look like if it were tagged correctly and displayed by a program that ignores the orienta-
tion tag:
1 2 3 4
888888 888888 88 88
88 88 88 88
8888 8888 8888 8888
88 88 88 88
88 88 888888 888888
5 6 7 8

88 88 88 88 88 88 88 88
88 8888888888 8888888888 88
jpegexiforient output the Exif Orientation Tag in a JPEG Exif file. With the options -1 .. -8, it can also be used to set the tag.
OPTIONS
--help display this help and exit
--version
output version information and exit
-n Do not output the trailing newline
-1 .. -8
Set orientation value 1 .. 8
