Ubuntu How to run a program in the background?

Question

ubuntu

Through ssh on the server I run the program, I cut down the ssh client, the program (server) is cut down

Answer 1

You can use nohup, then if the ssh connection is broken, the script will continue to work
# nohup sh program_name.sh & In this case, the script output will
go to the file nohup.out
there is no longer a control terminal for it:
# ps -C sh -o pid,sid,tname,cmd
Here we will see something like:
6955 4111 ? program_name.sh
Next run:
# ps -js 4111
and you will get more information about the running process
Or study the screen command, it will launch a virtual terminal that will not fall off when you disconnect the ssh session.
