Before you introduce job management, you need to know that job management is used in the bash environment. This means "when the login system is acquired bash shell , under a single terminal interface, multiple jobs are managed simultaneously". It should be understood that when you manage a job, each job is actually bash the current subroutine , which is related to each other. We cannot manage it in a way that is managed by tty1 the tty2 environment bash .Put the command directly in the backgroun
