How, can I hide background process's output?

When you submit the background process you can redirect the output to a file ect..

this_process.ksh > /dev/null &

this_process.ksh > /home/mine/this_process.dat &

Hope this helps!

No, I mean ... I need use like:
ssh --help &
Only one command, not a script, some programs like "ssh" can't use "> file", so
how can I hide this output?

To supress the output redirect either standard out or standard error.

The following works on my system. This is redirecting standard err.

Code:

ssh --help 2> /dev/null &

This is redirecting standard out and will show the output as the help is sent to standard error.

Code:

ssh --help 1> /dev/null &
