How to send an application to the background with a key combinatiion

[calande]

Hello,

I had a look at the job basics in linux (linuxreviews.org/beginner/jobs/) but I don't know how to send a job to the background when the command is already run and I don't have the prompt because the application is running. To run a new command, I would have to stop the application first... I'm searching for a key combination that doesn't stop my application, but sends it to the background and gives me the prompt to run other commands.
Thanks!

Hi there,

The combination you are looking for is control+Z. That will suspend the job. If you want it back use 'fg' and if you want it to keep running in the background use 'bg'.

Check the man pages for these commands to see how to switch between two tasks and let us know how you get on.

Hi,

Thanks, actually, I don't want to stop the application (it's a process that streams video). How can I send it to the background without stopping it?
Thanks,

Hi there,

You have two choices: the one above is to stop it temporarily and use the 'bg' command to continue it in the background. The other is to start the program with an '&' at the end of the command line to start it in the background.

I don't know of any way to take if from running in the foreground to running in the background in a single step.

Let us know how you get on

Thanks, nevermind. None of these solutions will work, because I can't afford to stop the program from streaming, not even for a few seconds. Also, if I append & at the end of the command, the program returns an error message and won't start streaming. That's not a big deal anyway
Thanks again.

You need to have a space between the command and &

Another way is to start your command in a screen session.
