I know how to redirect output and how to suppress them in bash. Now, suppose I accidentally forgot to append the output redirection part to the command (e.g.
> /tmp/mystdout) and my background process is already running for a while, can I still change to where
stderr are being written to? I really would like not to kill and restart the application.
To be more specific as asked by Gilles in his comment, I would like to fiddle with it in these scenarios in specific:
- wrong output file
- forgot to redirect
or a combination of both
E.g. I have Apache running and I can see the file descriptors:
/proc/8019/fd/0 -> /dev/null /proc/8019/fd/1 -> /dev/null /proc/8019/fd/2 -> /var/log/apache2/error.log
