    but can you use diff to visualize the differences, or even better, some tool as vbindiff.

    update: Include also the diff between ./two.out and the file generated when you use stdout_file to redirect the output to a file.

      Yes, Salva, I can and I did.
      BUT:
      the file is 3500 lines in size and also contains stuff I'll not post here... :-)

      I can send it to you as an eMail - but don't see the value.
      The files are identical, besides the fact that STDOUT has that section missing.

      thanks for your help!!!

      update: /tmp/ssh_del_$$.txt is COMPLETE
      two.out is complete
      STDOUT misses a block of lines

        Ah, from your post Re^2: Net::OpenSSH loosing lines ins reply, I understood "/tmp/ssh_del_$$.txt" was also missing some lines even if the file size was the same!

        if STDOUT were completely empty, I would suspect of Sys::SigAction doing something funny to STDOUT, but you say that the line numbers are there... I can not imagine how that could happen. Is like if $_ were changing from one call to the next?

        You can try reducing the script, first removing Net::OpenSSH from it. You already have the output on the /tmp/ssh_del_$$.txt files, so you don't need to retrieve them again.
