常用示例
Kill all processes
pkill [process_name]
Kill processes with exact name match
pkill -x [exact_name]
Kill processes owned by a specific user
pkill -u [username] [process_name]
Send a specific signal
pkill -[SIGTERM] [process_name]
Kill processes matching a pattern
pkill -i [pattern]
Kill the most recently started
pkill -n [process_name]
Kill the oldest
pkill -o [process_name]
说明
pkill sends signals to processes based on their names and other attributes. Unlike kill which requires process IDs, pkill uses pattern matching to identify target processes, making it more convenient for common process management tasks. By default, pkill sends SIGTERM (signal 15) to terminate processes gracefully. The pattern is matched against the process name (the executable name), but with -f it matches against the full command line including arguments. The command is particularly useful in scripts and for quickly terminating processes without first looking up their PIDs using ps or pgrep. Multiple selection criteria can be combined to precisely target specific processes.
