kill(1)
NAME
kill − terminate a process with extreme prejudice
SYNTAX
kill [ − signo ] processid ...
DESCRIPTION
The kill command sends signal 15 (terminate) to the specified processes. If a signal number preceded by ’−’ is given as first argument, that signal is sent instead of terminate. For further information, see signal(2). This will kill processes that do not catch the signal; in particular ’kill −9 ...’ is a sure kill.
By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are signaled.
The process number of an asynchronous process started with ’&’ is reported by the shell. Process numbers can also be found by using ps(1).
The killed processes must belong to the current user unless he is the superuser. To shut the system down to single user mode, use the opser (operator services) program. For further information, see opser(8) and ULTRIX-11 System Management Guide.
