The command "killall -INT ${process_name}" is used to send an interrupt signal (SIGINT) to a specific process or group of processes specified by the "process_name" parameter.

Here is a breakdown of the command:

• "killall" is a Linux command used to send signals to multiple processes, terminating them or modifying their behavior. In this case, it is used to send an interrupt signal.
• "-INT" is an option/flag that specifies the specific signal to be sent. "INT" stands for interrupt, which is the signal number 2. Sending an interrupt signal to a process usually requests it to gracefully terminate. If the process does not handle this signal or does not terminate within a specific time, it may be forcibly terminated.
• "${process_name}" is a placeholder for the actual name of the process or processes to be targeted. It could be the name of a running program or a regular expression representing a group of processes.

In summary, this command kills or interrupts the processes with the specified name or matching a specific pattern, asking them to terminate voluntarily.
