This is a Linux specific doubt.
I start a process, that waits for keyboard input. I press Ctrl+z, and the process halts. Then I write 'bg' in the console and the process keeps running, in the background.
Now I want to send keyboard input to the process but I don't know how. Do I need somehow to give focus to the process, and then the input? Or is there any command line to do so?
Thank you. ;)
