Thanks a lot. I tried and this is what I get, the result did not change. It doesn't make any sense.

Code:
erden@erden-linux:~/Data/try$ paste -d '\t' t[0-3]
800.0000800.000000.05562-0.054032
799.0000799.000000.05573-0.053876
798.0000798.000000.05547-0.053918
797.000000	-0.055687	797.000000	-0.052766	797.000000	-0.054031

Code:
awk ' { I[$1] = I[$1]?I[$1] " " $2:$0 }
 END {
   for( i in I )
     print I[i]
 }
' file*

$ ./T   
800.000000	0.002744 0.000261 -0.060552

Thanks a lot scottn. There is something wrong with my data files I guess. I did not work with my data. Here is the output:
Code:
./T

 -0.053876	-0.055739
 -0.053918	-0.055475
797.000000	-0.055687 -0.052766 -0.054031
 -0.054032	-0.055621

I don't know what is wrong? I uploaded my files before, if anyone is willing to try.

Thanks a lot.

Hi erden.

The problem is that you have ^M characters in your input files.

When they're removed it works.

Quick fix:

Code:
cat t* | tr -d '\015' | awk '
 {
   I[$1] = I[$1]?I[$1] " " $2:$0
 }

 END {
   for( i in I)
     print I[i]
 }
'

Hi.

Using the options for cat to see invisible characters for (your file t1) data1:
Code:
% cat -A data1
800.000000^I-0.055621^M$
799.000000^I-0.055739^M$
798.000000^I-0.055475^M$
797.000000^I-0.055687$
$

The ^M typically comes from DOS-style files, or using a DOS-style editor. There are a number of utilities to remove the ^M character; so afterwards:
Code:
% cat -A data1
800.000000^I-0.055621$
799.000000^I-0.055739$
798.000000^I-0.055475$
797.000000^I-0.055687$
$

Note that file ends with an empty line:
Code:
% wc -l data1
5 data1

I suspect that once you clean up your files, things will look better (pun intended).

Utilities to consider (a sample from a GNU/Linux system):
Code:
tofrodos - Converts DOS <-> Unix text files, alias tofromdos
flip - convert text file line endings between Unix and DOS formats
tr -d '\015' <your-filename >some-other-filename

Best wishes ... cheers, drl

Thanks scottn, thanks drl,

I got these files from a windows program. When I remove ^M chars it worked!

Thanks a lot, I really appreciate it.
All the best,
Erden
