Which kill signal is associated with interrupting a process?

The signal associated with interrupting a process is the SIGINT signal. This signal is typically generated when a user wants to interrupt a running program, commonly by pressing Ctrl+C in a terminal. This action sends a SIGINT signal to the foreground process, instructing it to terminate its execution gracefully.

In most cases, a program can handle the SIGINT signal in a custom way, allowing it to perform cleanup operations before exiting. This could be closing files, saving data, or notifying other processes, depending on how the program is designed. This aspect distinguishes it from other signals like SIGKILL, which forcefully terminates a process without the opportunity for cleanup, or SIGTERM, which also requests termination but can be caught and handled.

The SIGINT signal is specifically designed for user-generated interrupts, making it the correct choice for identifying a signal that interrupts a process.
