Linux process management
Windows has a task manager to manage processes, and Linux also has corresponding commands to manage processes.
View processes
ps command: View static process statistics
Example
top command
View process dynamic information, refresh every 3s
pgrep command
Filter query process information
pstree command
View process tree
Control process
job command
View the process tasks running in the background of the current terminal
bg command
To resume the task suspended in the background and continue to run in the background, you need to specify the task number as a parameter
kill command
Terminate the process by PID. When there are no specific options, send a termination signal to the program and exit normally.
killall command
Killing by process name is more convenient when killing multiple processes with the same name.
pkill command
Termination under specific conditions, similar to pgrep
pkill -9 -U “root”
