To view and manage processes on Debian, you can use several commands in the terminal. The most common command to view running processes is ps, which stands for process status. For example, ps aux will list all running processes with detailed information about each one, including the user running the process, the PID (process ID), CPU and memory usage, and the command that started the process.
Another useful command is top, which provides a dynamic real-time view of running processes. When you run top, it displays a list of processes and updates it periodically. You can sort the processes by various criteria like CPU usage, memory usage, and PID.
To manage processes, you can use the kill command to terminate a process by its PID. For example, kill 1234 will send a termination signal to the process with PID 1234. If the process does not terminate, you can use kill -9 1234 to send a stronger signal.
Additionally, htop is a more interactive version of top that allows you to scroll through the list of processes, filter them, and even kill processes directly from the interface without opening a new terminal window.
For managing processes in a more graphical way, you might consider using a system monitor tool like gnome-system-monitor if you are using the GNOME desktop environment.
In a cloud environment like Tencent Cloud, you can manage processes on your Debian instances using the same commands via SSH. Tencent Cloud also offers monitoring and management tools that can help you keep an eye on your instances' performance and resource usage, which indirectly aids in process management by providing insights into system health and performance metrics.
