Which command is used to terminate processes?

The command used to terminate processes in Linux is 'kill.' This command allows users to send specific signals to processes, with the most common signal being the TERM signal, which requests a process to gracefully shut down. Additionally, 'kill' can also send other signals, such as KILL, which forces the termination of a process without allowing it to clean up resources or perform any shutdown activities.

Using 'kill' is essential because it provides granular control over how a process is terminated, allowing users to either request a clean shutdown or to forcekill a process if it is not responding.

The other options do not correspond to valid Linux commands. 'stop' is not a standard command for terminating processes, 'terminate' is not a recognized command in this context, and 'end' does not have any functionality related to process termination. Thus, 'kill' is the correct and most widely used command for this purpose.
