How to reactivate process sent to background
I am currently running lots of software on my Linux RedHat 8.0 server, among those is a Half-Life Server.
Now, when I start this server I type nohup in front of the name so that it won't shut down when I log off the SSH client, I don't know if nohup is needed but it works fine. Anyway, when I log back into the machine, of course the server is running in the background, vissible in "top" but not in PS, my question is:
Can I reactivate the process in some way so that I can type commands to the server from SSH without having to restart it, eneter the commands, and then send it to the background ?
