What is the primary difference between killall and pkill?

killall sends signals by PID, while pkill sends by name.

killall is used for background jobs, while pkill is for foreground processes.

killall matches the exact process name, while pkill uses regular expressions.

killall can only send SIGKILL, while pkill can send any signal.
