methods that have little impact on the operating system.
Stage 1: Kill the process on the local machine.
System Engineers can directly interrupt commands on Unix systems and use related commands to kill abnormal processes. For example, you can press the DEL key, Ctrl + D key, and Break key on the disk to kill the pro

Named pipes must be created explicitly and will not disappear (the RM command can be removed).The proc file is a pseudo-file used to access kernel information. For example, if a process ID is 1952, the process-related information can be found in a file in the/proc/1952 directory.The VFS (virtual file system) implements the details of file processing.24th Directory Operations~ Repres

Linux and Unix are multi-task operating systems, that is, a system can run multiple tasks (processes) within the same period of time ). In this new blog series, I will list related Linux and Unix job control commands, you can execute multiple tasks in Bash, Korn, and POSIX shell.

Int setpgid (pid_t pid, pid_t pgid );
// Return: if the request succeeds, the value is 0, and the error value is-1.
This sets the pid process's process group ID to pgid. If the pid is 0, the caller's process ID is used. In addition, if the pgid is 0, the process ID specified by the pid is used as the process group ID. If the two parameters are equal, the process specified by the pid becomes the process group leader.
A process can only set process group I D for itself or it
