Question

As all we know, in bash, if we start a process, “bash another.sh” for example, main bash will wait for another.sh to finished, then execute the remained code in main bash, Is there any method to exit the main shell before another.sh returns?

Answer 1

If you want to be able to log out of the shell before the process has finished you can prepend xls’s statement with nohup:

nohup bash another.sh &

Then your newly started process won’t receive SIGHUP when logging out and will continue to run in the background.
