How to find and kill processes on Linux?

To find and kill processes on Linux, you can use commands like ps, grep, and kill.

The ps command is used to display information about active processes. For example, ps aux will list all running processes with detailed information.

To find a specific process, you can pipe the output of ps to grep. For instance, to find a process named "myprocess", you would use:

ps aux | grep myprocess

Once you've identified the process you want to terminate, you can use the kill command. Processes are identified by a unique number called a Process ID (PID). You can kill a process by its PID using:

kill PID

For example, if the PID of "myprocess" is 12345, you would type:

kill 12345

If the process doesn't terminate with a regular kill command, you might need to use kill -9 PID to force it to stop.

In the context of cloud computing, managing processes is crucial for maintaining efficient resource usage on cloud servers. For example, on Tencent Cloud's CVM (Cloud Virtual Machine), you can use these commands to manage processes running on your virtual servers, ensuring optimal performance and security.
