Putting Jobs in the Background

Using nohup command & is the way in which you start a job (command) which will not accept the hangup signal when you logout (nohup) and will run in the background (&).

Of course you need to remember to put nohup before your command and the & after your command. If you forget all is not lost you can do the same thing with the following commands: CTRL-z, fg, bg, jobs and disown.

• CTRL-z will put a process into the background and suspend it.
• fg [job id] will bring a process back to the foreground.
• bg [job id] will start a background job (note that it is still attached to your terminal and so will hang up if you logout)
• disown %[job id] will remove [job id] from the list of jobs you own which means that the job will continue to run after you logout.
• jobs will list the jobs you own.
  • You can use job ids with commands like kill if you use the % i.e. kill %[job id] will kill [job id].
  • The [job id] is not the process id.

[1]+ Stopped ./test.sh
the above is the result of a CTRL-z the [job id] is the number in the square brackets.
So you will then need to start the job in the background with bg which outputs:
[1]+ ./test.sh &
Then disown process with disown %1 so you can logout
