Just be careful, chatGPT is a black box, you don’t know how it resolves your question. Furthermore on a question when you lack some knowledge, your no able to evaluate the quality of the answer.

For instance, I’ve just knock down chatGPT with these questions:

ChatGPT knock down on IT expert technical questions
The previous discussion is a french discussion but you’ll find the translation here (Translated with www.DeepL.com/Translator (free version)):

Me:

in a linux shell, what is the difference between the command :
(java myfile &)
and the command :
nohup java myfile &

ChatGPT:

The “(java myfile &)” command executes the “myfile” file using the Java program in the background, allowing the user to continue using the command line while the file is running.

The “nohup java myfile &” command is similar, but it uses the “nohup” tool to prevent the process from being interrupted when the user logs out or closes the shell session. This means that the process will continue to run even if the user logs out or closes the terminal.

Me:

yet the command when I use :
(java myfile &)
if I close my terminal, or if I log out, the command continues to run. And it seems that this is due to the fact that java myfile & is in brackets.

ChatGPT:

You are right, using parentheses “(java myfile &)” also ensures that the process continues to run even after the terminal is closed or the user logs out. The parentheses create a group of processes that is run in the background, so that the main process (the shell) does not block the execution of the child process (java myfile). The & at the end of the command also indicates that the process should be run in the background.

In summary, the command “nohup java myfile &” and “(java myfile &)” have the same effect, i.e. to make the process continue to run even after the terminal is closed or the user logs out.
