Keep Java programs running in the background (for example, the daemon continues to run after Putty is closed)

If the Java-jar xxx.jar& command is executed in the terminal, Xxx.jar will also end up running when the terminal is closed, but if the nohup java-jar xxx.jar& command is executed, the program will run in the background, and it is worth noting that The program console output is then transferred to the Nohup.out file.

attached: nohup command Reference nohup command

Purpose: To run the command without hanging off.

Syntax: Nohup Command [Arg ...] [&]

Description: The nohup command runs commands specified by the command parameter and any related ARG parameters, ignoring all hang-up (SIGHUP) signals. Use the Nohup command to run a program in the background after logging off. To run the Nohup command in the background, add & (the symbol representing "and") to the end of the command.

。 If the nohup.out file for the current directory is not writable, the output is redirected to the $HOME/nohup.out file. If no file can be created or opened for appending, then the command specified by the commands parameter is not callable. If the standard error is a terminal, then all output of the specified command to the standard error is redirected to the same file descriptor as the standard output.
