Linux noup command runs the program in the background

The linux noup command runs the program nohup in the background <program name> & after the console logout, the process continues to run and serves as a daemon (although it is not a strict Daemon ). After the nohup command is used, the standard output of the original program is automatically changed to the nohup. out file in the current directory, which plays a role in log and implements the complete daemon function.

After a command is directly input under shell, shell places the process to the foreground for execution. If you want to put the process in the background for execution, you need to add the "&" symbol at the end of the command line. The following command is executed in the background and downloaded from ftp.isc.org. $ Fetch ftp://ftp.isc.org/pub/inn/inn-1.7.2.tar.gz & when the program is already running on the foreground, you can use ^ Z to suspend the program and pause it.
