Learn to use nohup and & to easily manage processes

In Unix/Linux systems, we often need to run some long-running tasks or services, such as uploading and downloading files, backing up data, scheduled tasks, etc. In order to allow these tasks to run in the background and not be affected by terminal closing, we can use nohup and & to manage the process so that the task can continue to run and not be affected by the terminal session.

nohup is a very useful command for running commands in the background without hanging up. Even if the terminal is closed, it will not affect the running of the process. The nohup command is very simple to use. Just add nohup before the command you want to run. For example, if we want to execute a script run.sh that takes a long time, we can execute it like this: nohup ./run.sh &. This way the script will run in the background and will not be interrupted even if the terminal is closed.

In addition, the task can be run in the background by combining the & symbols. When we execute a command and want it to run in the background, we can add & symbols at the end of the command. For example, if we want to run a Python script test.py, we can use the command python test.py & to run it in the background.

Using nohup and & to manage processes can improve work efficiency and avoid the inconvenience of manually maintaining a terminal session. In our daily work, we often encounter long-running tasks. Using nohup and & can make it easier for us to manage these processes and improve work efficiency. Remember to monitor the running status of the process when using it to avoid unnecessary waste of resources.

In short, learning to use the nohup and & commands can make it easier for us to manage processes, improve work efficiency, and avoid the impact of terminal session closing on tasks. I hope the above introduction will be helpful to everyone, so that you can better utilize the functions of Unix/Linux system and improve work efficiency.
