Which command is used to terminate a shell process in Linux?

The command used to terminate a shell process in Linux is "kill." This command allows users to send signals to processes, with the default signal being SIGTERM. When this signal is sent, it requests the process to terminate gracefully, allowing it to clean up resources and save state, if applicable.

In addition to SIGTERM, the kill command can also be used to send SIGKILL, which forcefully stops a process without allowing it to clean up. The command is versatile and can be used with various options to specify which process to terminate, typically by providing the process ID (PID).

Other options listed, such as "terminate," "stop," and "end," are not standard commands recognized by the Linux shell for terminating processes. They do not exist in the context of managing processes, while "kill" is a well-established command integral to the Linux operating system for process management. Understanding how to use the kill command is essential for managing processes effectively in Linux environments.
