Prevent a background process from being stopped after closing SSH client
I have a program that takes a lot of time to finish.
It is running as root over ssh.
I want it to continue to run after I logout,is this possible and how would I achieve this?
Assuming that you have a program running in the foreground, press ctrl-Z, then:
+ Stopped myprogram $ disown -h %1 $ bg 1 + myprogram & $ logout
If there is only one job, then you don't need to specify the job number. Just use
disown -h and
You press ctrl-Z. The system suspends the running program, displays a job number and a "Stopped" message and returns you to a bash prompt.
You type the
disown -h %1 command (here, I've used a
1, but you'd use the job number that was displayed in the
Stopped message) which marks the job so it ignores the
SIGHUP signal (it will not be stopped by logging out).
Next, type the
bg command using the same job number; this resumes the running of the program in the background and a message is displayed confirming that.
You can now log out and it will continue running..
