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.
See Alsocsh(1), ps(1), kill(2), sigvec(2)kill(1)

KILL(1) BSD General Commands Manual KILL(1)NAME
kill -- terminate or signal a process
SYNOPSIS
kill [-s signal_name] pid ...
kill -l [exit_status]
kill -signal_name pid ...
kill -signal_number pid ...
DESCRIPTION
The kill utility sends a signal to the process(es) specified by the pid operand(s).
Only the super-user may send signals to other users' processes.
The options are as follows:
-s signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-l [exit_status]
Display the name of the signal corresponding to exit_status. exit_status may be the exit status of a command killed by a signal (see
the special sh(1) parameter '?') or a signal number.
If no operand is given, display the names of all the signals.
-signal_name
A symbolic signal name specifying the signal to be sent instead of the default TERM.
-signal_number
A non-negative decimal integer, specifying the signal to be sent instead of the default TERM.
The following pids have special meanings:
-1 If superuser, broadcast the signal to all processes; otherwise broadcast to all processes belonging to the user.
0 Broadcast the signal to all processes in the current process group belonging to the user.
Some of the more commonly used signals:
1 HUP (hang up)
2 INT (interrupt)
3 QUIT (quit)
6 ABRT (abort)
9 KILL (non-catchable, non-ignorable kill)
14 ALRM (alarm clock)
15 TERM (software termination signal)
kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill argu-
ments. See csh(1) for details.
SEE ALSO csh(1), pgrep(1), pkill(1), ps(1), kill(2), sigaction(2), signal(7)STANDARDS
The kill function is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

I'm trying to kill a process which is in sleep mode and the parent PID is 1 but I can't kill it with "kill -9" command. Is there a way to kill this process without rebooting?
Any help will be appreciated.

We should put an end to saying "orphan", "kill child", "zombie".
Anyone,
We should change the awful metaphors used in the language of managing Unix processes. I believe that this still humbly local initiative hides a great importance of how the world of Unix looks and feels to every user.

Hi,
In a bash script, I'm using kill -0 to test if I have permission to kill a process. There are 3 cases:
- the process exists and I have permission: OK
- the process doesn't exist and it's OK (because I decided to ignore processes that are already dead).
- I don't have permission and I want... (13 Replies)
