kill(1) General Commands Manual kill(1)
Name
kill - send a signal to a process
Syntax
kill [-sig] processid...
kill -l
Description
The command sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first
argument, that signal is sent instead of terminate. For further information, see
The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be caught.
By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
signaled. This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.
The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using It
allows job specifiers ``%...'' so process ID's are not as often used as arguments. See for details.
Options
-l Lists signal names. The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
prefix.
