Merging columns from multiple files
Hello,

I have a number of tab delimited data files consists of two columns. Like that:

Code:
File1
800.000000	0.002744
799.000000	0.002517
798.000000	0.002836
797.000000	0.002553

FIle2
800.000000	0.000261
799.000000	0.000001
798.000000	0.000551
797.000000	0.000275

File3
800.000000	-0.060552
799.000000	-0.060650
798.000000	-0.060206
797.000000	-0.060329

...

FileN

I would like to display the data in one file:

Code:
                         File1		FIle2		File3     ... FileN
800.000000	0.002744	0.000261	-0.060552
799.000000	0.002517	0.000001	-0.060650
798.000000	0.002836	0.000551	-0.060206
797.000000	0.002553	0.000275	-0.060329

What is the best way to do that?

Thanks a lot!
Erden

PS - I tried `paste *` this is what I get:

Code:
800.0000800.0000000027440.0033342
799.0000799.0000000025170.0045670
798.0000798.0000000028360.0048366
797.0000797.0000000025530.0025539

Also I searched similar topics, but nothing worked out for me.

Didn't work. This is the output

Code:
paste -d" " File1 File2 File3

 800.000000     0.0033342
 799.000000     0.0045670
 798.000000     0.0048366
 797.000000     0.0025539

Somehow it takes first column of the first file and second column of the last file. Not the others Thanks anyway.

When I copy and paste from here it worked. Forum changes tab chars with space.

But I did copy and paste data from my original long files and this time I get really weird results. Now it worked for just last column. It is crazy!

Code:
 800.000000     -0.054032
 799.000000     -0.053876
 798.000000     -0.053918
797.000000	-0.055687 797.000000	-0.052766 797.000000	-0.054031


I attached my files, if anyone wants to check.

I am using ubuntu 9.10 and bash

Thanks.
