Re: 're'-redirecting STDOUT back to STDOUT after writing to a file

Thanks, I have learned something. My conception was that STD* 
descriptors where sort of system constants. Now I see that you can 
query, rename and store them into other variables.

So storing old STDOUT and resetting when done with all the other stuff 
works perfect now.

Thanks again,
Matthias

Subject: 're'-redirecting STDOUT back to STDOUT after writing to a file

Hi,
   this might be a really stupid question. But, in a cgi-script I 
wanted to prevent an executable that I call from within the script from 
dumping output directly to the webpage.

This worked fine with 'open(STDOUT,">something-log.txt")'.
But now I want to write to the webpage again. 'open(STDOUT,">&STDOUT")' 
does not only look strange, well, it also doesn't work.

Thanks in advance,
Matthias
