Hi all, thanks for your help!!
I changed the
Code:
>> newfile

to
Code:
>newfile

, and the output its the same. I cant open the text file with gedit, and i cant open it with my software (which is suposed to do some analysis to the data).

But when i use
Code:
cat

, just like vgersh sugested, the data shows like its suposed to be. Here its the output from cat:

Code:

And thats correct, but the problem is the "format" of the file that creates, at the moment i cant open the file except with cat. Any ideas? maybe convert the file?

Maybe its because i need a plain text file and im getting some kind of "rich" text file?

There's a couple of questions you didn't answer:
  • Can you open the file in another editor (like vi)?
  • What is the output of file your_input_file?

And another couple of questions:
  • What OS are you using?
  • What shell are you using?

What is the output of file your_input_file ?
Code:
 
ASCII text, with very long lines, with CRLF line terminators

And the output of file my_output file is:
Code:
 
ASCII text

To the other question, yes, im able to open the file with vi and cat.
Im using ubuntu with bash shell.

Thanks!

Thanks for clearing that up Smilie

I'm with vgersh99, and know little about gedit.

You have the output you wanted (even if you can't read it in gedit). I presume that output served a bigger purpose than gedit.

Read the documentation for the editor. Perhaps there's a setting you could change to allow it to read the file.

My mistake, just double checked the output of "file my_output_file" and it shows:
Code:
$ file dm01new
dm01new: data

Is there a way to convert it to ASCII?

Browsing around found this:
Code:
 
strings old > new

And that solved my problem!!!!! Thanks for your help =D
