Test the respective roles of nohup and &

Start the front desk service , The log will be printed and cannot be entered in the current window
Suppose the command entered is ： XXXXX
Input nohup XXXXX & Command is enough .
To find out nohup and & Their respective functions , I did the following 4 Test and record the results ：

XXXXX	The foreground prints log information	Close the current window , Service stopped	ctrl+c After the operation , Service stopped	The process number of the service is not displayed
nohup XXXXX	The front desk does not print log information	Close the current window , The service doesn't stop	ctrl+c After the operation , Service stopped	The process number of the service is not displayed
XXXXX &	The foreground prints log information	Close the current window , Service stopped	ctrl+c After the operation , The service doesn't stop	Display the process number of the service
nohup XXXXX &	The front desk does not print log information	Close the current window , The service doesn't stop	ctrl+c After the operation , The service doesn't stop	The process number of the service is not displayed

Conclusion ：
nuhup Ensure that log information is not displayed in the foreground , And the service does not stop when the current window is closed ;
& Guarantee ctrl+c The operation service does not stop , Display the process number of the service

They are independent of each other , Guarantee of cooperative use ：
1. Do not display log information
2. Close the current window , The service doesn't stop
3.ctrl+c After the operation , The service doesn't stop
4. Display the process number of the service

notes ：nohup Make the log information not displayed , And stored in the current input path nohup.out In file .
