Editor to share with you the use of linux nohup commands to run the back-end program, I believe that most people do not know much, so share this article for you to learn, I hope you will learn a lot after reading this article, let's go to learn the method!

The full name of the nohup command is "no hang up", which can run the program in a way that ignores the hang signal, and the output information of the program being run will not be displayed to the terminal.

Whether or not the output of the nohup command is redirected to the terminal, the output is appended to the nohup.out file in the current directory. If the nohup.out file in the current directory is not writable, the output is redirected to the $HOME/nohup.out file. If there is no file that can be created or opened for append, the command specified by the command parameter cannot be called. If standard error is a terminal, the specified command is written to all outputs of standard error as standard output is redirected to the same file descriptor.

Syntax format: nohup [parameters]

Common parameters:

-- help online help-- version displays version information

Reference example

Use the nohup command to run the program in the background:

[root@linuxcool ~] # nohup bash linuxcool.sh &

Specify the output file, which is redirected to the linuxcool.com file:

[root@linuxcool ~] # nohup command > linuxcool.com 2 > & 1 above are all the contents of the back-end running program using linux's nohup command. Thank you for reading!
