How to Control foreground and background tasks in Linux

Article Title: how to control tasks in the front and back of Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Linux/Unix is different from Microsoft's platform. The biggest advantage is the real multi-user, multi-task. Therefore, there are also special management ideas in task management.

We know that in Windows, we either have a program running on the background as a service or stop the service. The program cannot be switched between the foreground and background. Linux provides fg and bg commands, allowing you to easily schedule running tasks.

Suppose you find it takes a long time to run a program on the front end, but you need to do other things, you can use Ctrl-Z to terminate the program, and then you can see the system prompt:

[1] + Stopped/root/bin/rsync. sh

Then we can schedule the program to the background for execution: (the number following bg is the job number)

# Bg 1

[1] +/root/bin/rsync. sh &

Run the jobs command to view running tasks:

# Jobs

[1] + Running/root/bin/rsync. sh &

If you want to call it back to the foreground, you can use

# Fg 1

/Root/bin/rsync. sh

In this way, you can only wait for the task to be completed on the console.
