pkill:tldr:032fe

The command "pkill "${process_name}"" is used to send a signal to terminate or stop a process based on its name or other attributes.

Here's an explanation of the command:

1. "pkill": It is a command-line utility in Unix-like operating systems that sends a signal to one or more processes specified by their names or attributes.

2. "${process_name}": It is a placeholder for the name or attribute of the process you want to terminate. You would replace "${process_name}" with the actual name of the process.

For example, if you want to terminate a process named "myapp", you would execute the command: "pkill myapp".

The "pkill" command searches for processes matching the given name or attributes and sends a termination signal (SIGTERM by default) to all the matching processes. This signal instructs the process to gracefully stop and clean up before termination.

Note that the "pkill" command can also be used with additional options to specify different signals or filter processes based on attributes like user, group, or process ID.
