# run in the background through the "&" symbol:

Java-jar xxx.jar &

# run in the background through the "nohup" command:

Nohup java-jar xxx.jar &

Copy the code

The nohup command means to run the command without hanging up.

Features: when the user exits or the terminal is closed, the operation of the program will not be affected.

Description: when you run a task with the nohup command, all output from this task will be redirected to the nohup.out file by default, unless you specify another output file. Specify the output file method as follows:

# redirect the output to the xxx.log file:
