How do I stop a nohup process from running?
16 Answers. When using nohup and you put the task in the background, the background operator ( & ) will give you the PID at the command prompt.

What does running nohup do in Windows 10?
Running nohup does the following things: It ignores the SIGHUP signal for the program. (This behavior, however, can be changed inside the program. More on this exception later in the article.)
