8.5.1 Kill a process
Run top to see what process is acting funny. Press `P' to sort by
CPU usage, `M' to sort by memory, and `k' to kill a process. Alternatively,
BSD-style ps aux | less or System-V-style ps -efH |
less may be used. The System-V-style syntax displays parent process IDs
(PPID) which can be used for killing zombie (defunct) children.
Use kill to kill (or send a signal to) a process by process ID,
killall to do the same by process command name. Frequently used
signals:
1: HUP, restart daemon
15: TERM, normal kill
9: KILL, kill hard
