Linux task control (bg job fg nohup ) I. Introduction The biggest advantage of Linux/Unix which is different from Microsoft platform is real multi-user and 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

How to use FG to quickly return to vim?When you use VIM to modify a parameter in a file, you cannot remember the parameters for a long time. It often appears that when we just opened this file with Vim, we forgot the parameters just now. At this point we need to temporarily exit this file to find parameters in a directory. Or, you have multiple open actions to close the same file.So how do you make this kind of operation easier and quicker?Now if you

BG and FG commands for LinuxAs we all know, on Windows, we either have a program running in the background as a service, or stop the service. Instead of allowing the program to switch between foreground and background. Linux provides FG and BG commands, allowing us to easily schedule running tasks.Suppose you find that a program running in the foreground takes a long time, but you need to do something else,

/-name Password (background perform task)Note: In effect, the use of the BG command is the same as adding the symbol "" after the instruction. For example, use to place the Find/-name password in the background executionFG: Used to put background jobs (jobs that are running in the background or suspended in the background) to the foreground terminal to run.Example:FG 1 (convert task to foreground execution)Find/-name password (foreground execution command)Nice: Used to start other programs wit

There are two ways to put a process into the background under Linux:The first way: means that the command executes the program in the background, which is equivalent to minimizing the program in Windows.The second way: Execute a command, for example: top, and then press CTRL + Z shortcut key, put it into the background to execute.The difference between the two ways is: the first way: into the background of the process is still executing, the second way: Ctrl + Z into the background of the execut
