Hi everyone!

Well, this is the thing.. I sent a process's stdout to /dev/null. This process
is very time consuming and after a week it keeps running, what I need is
to switch the stdout back to screen to see what's going on.
Anyone know if it's possible and how to do it?

Thanks and regards.

afaik, you cannot do that. Once the process starts with all the file descriptors in place, unix will not allow you to do this. You can setup some sort of mechanism where on receiving a signal, your process also writes whatever it is writing to stdout to another file.
But it will be a lot of work, so it just might make more sense to redirect stdout to a file and keep truncating it every so often (you could have a cronjob) till you need to see what the process is doing. When you do, stop truncating the file and whatever you need to check is just waiting in that file.

Hi


I m not sure that this is your requirement . however i m trying if it works for you its good !!!!

the solution to your problem is using tee command but for that you will have to run the code from beginning
not in middle . suppose you are using less command to see any file
then you can send the output to the file and also to your terminal as follows

less abc.log | tee /dev/pts10 xyz.txt| less

Ok, thanks for the help. As I understand the less would be an option, but before the command was triggered. Anyway, I will kill the process and re-run it with stdout>/dev/tty0. Logging to a file is not an option, cause I'm running fcrackzip, and its going to fill my hard disk in minutes. ;-)

Thanks again.
