pkill


pkill -f node

In Linux, various signals (e.g., SIGHUP, SIGUSR1) have a default behavior of "terminating the process if no handler is registered," which can cause large-scale service outages. Therefore, the new pkill feature below only sends signals to processes that have handlers registered for those signals.


pkill --require-handler (-H)
kill -r

Preventing outages with pkill's new --require-handler flag

A safer approach to using signals in production systems, avoiding service outages when signal handlers are removed.
