+NAME
+ kill - terminate or signal processes
+
+SYNOPSIS
+ kill -s signal_name pid ...
+
+ kill -l [exit_status]
+
+
+
+ kill [-signal_name] pid ...
+
+ kill [-signal_number] pid ...
+
+
+DESCRIPTION
+ The kill utility shall send a signal to the process or
+ processes specified by each pid operand.
+
+ For each pid operand, the kill utility shall perform
+ actions equivalent to the kill() function defined in the
+ System Interfaces volume of IEEE Std 1003.1-2001 called
+ with the following arguments:
+
+ The value of the pid operand shall be used as the
+ pid argument.
+
+ The sig argument is the value specified by the -s
+ option, - signal_number option, or the - sig-
+ nal_name option, or by SIGTERM, if none of these
+ options is specified.
+
+OPTIONS
+ The kill utility shall conform to the Base Definitions
+ volume of IEEE Std 1003.1-2001, Section 12.2, Utility
+ Syntax Guidelines, except that in the last two SYNOPSIS
+ forms, the - signal_number and - signal_name options are
+ usually more than a single character.
+
+ The following options shall be supported:
+
+ -l (The letter ell.) Write all values of signal_name
+ supported by the implementation, if no operand is
+ given. If an exit_status operand is given and it
+ is a value of the '?' shell special parameter
+ (see Special Parameters and wait() ) correspond-
+ ing to a process that was terminated by a signal,
+ the signal_name corresponding to the signal that
+ terminated the process shall be written. If an
+ exit_status operand is given and it is the
+ unsigned decimal integer value of a signal num-
+ ber, the signal_name (the symbolic constant name
+ without the SIG prefix defined in the Base Defi-
+ nitions volume of IEEE Std 1003.1-2001) corre-
+ sponding to that signal shall be written. Other-
+ wise, the results are unspecified.
+
+ -s signal_name
+
+ Specify the signal to send, using one of the sym-
+ bolic names defined in the <signal.h> header.
+ Values of signal_name shall be recognized in a
+ case-independent fashion, without the SIG prefix.
+ In addition, the symbolic name 0 shall be
+ recognized, representing the signal value zero.
+ The corresponding signal shall be sent instead of
+ SIGTERM.
+
+ -signal_name
+
+ Equivalent to -s signal_name.
+
+ -signal_number
+
+ Specify a non-negative decimal integer, sig-
+ nal_number, representing the signal to be used
+ instead of SIGTERM, as the sig argument in the
+ effective call to kill(). The correspondence
+ between integer values and the sig value used is
+ shown in the following table.
+
+ The effects of specifying any signal_number other than
+ those listed in the table are undefined.
+
+
+ signal_number sig Value
+ 0 0
+ 1 SIGHUP
+ 2 SIGINT
+ 3 SIGQUIT
+ 6 SIGABRT
+ 9 SIGKILL
+ 14 SIGALRM
+ 15 SIGTERM
+
+ If the first argument is a negative integer, it shall be
+ interpreted as a - signal_number option, not as a nega-
+ tive pid operand specifying a process group.
+
+OPERANDS
+ The following operands shall be supported:
+
+ pid One of the following:
+
+ A decimal integer specifying a process or process group
+ to be signaled. The process or processes selected by
+ positive, negative, and zero values of the pid operand
+ shall be as described for the kill() function. If
+ process number 0 is specified, all processes in the cur-
+ rent process group shall be signaled. For the effects of
+ negative pid numbers, see the kill() function defined in
+ the System Interfaces volume of IEEE Std 1003.1-2001. If
+ the first pid operand is negative, it should be preceded
+ by "--" to keep it from being interpreted as an option.
+
+ A job control job ID (see the Base Definitions volume of
+ IEEE Std 1003.1-2001, Section 3.203, Job Control Job ID)
+ that identifies a background process group to be sig-
+ naled. The job control job ID notation is applicable
+ only for invocations of kill in the current shell execu-
+ tion environment; see Shell Execution Environment .
+
+ exit_status
+ A decimal integer specifying a signal number or
+ the exit status of a process terminated by a sig-
+ nal.
+
+
+STDIN
+ Not used.
+
+INPUT FILES
+ None.
+
+ENVIRONMENT VARIABLES
+ The following environment variables shall affect the
+ execution of kill:
+
+ LANG Provide a default value for the internationaliza-
+ tion variables that are unset or null. (See the
+ Base Definitions volume of IEEE Std 1003.1-2001,
+ Section 8.2, Internationalization Variables for
+ the precedence of internationalization variables
+ used to determine the values of locale cate-
+ gories.)
+
+ LC_ALL If set to a non-empty string value, override the
+ values of all the other internationalization
+ variables.
+
+ LC_CTYPE
+ Determine the locale for the interpretation of
+ sequences of bytes of text data as characters
+ (for example, single-byte as opposed to multi-
+ byte characters in arguments).
+
+ LC_MESSAGES
+ Determine the locale that should be used to
+ affect the format and contents of diagnostic mes-
+ sages written to standard error.
+
+ NLSPATH
+ Determine the location of message catalogs for
+ the processing of LC_MESSAGES .
+
+
+ASYNCHRONOUS EVENTS
+ Default.
+
+STDOUT
+ When the -l option is not specified, the standard output
+ shall not be used.
+
+ When the -l option is specified, the symbolic name of
+ each signal shall be written in the following format:
+
+
+ "%s%c", <signal_name>, <separator>
+
+ where the <signal_name> is in uppercase, without the SIG
+ prefix, and the <separator> shall be either a <newline>
+ or a <space>. For the last signal written, <separator>
+ shall be a <newline>.
+
+ When both the -l option and exit_status operand are
+ specified, the symbolic name of the corresponding signal
+ shall be written in the following format:
+
+
+ "%s\n", <signal_name>
+
+STDERR
+ The standard error shall be used only for diagnostic
+ messages.
+
+OUTPUT FILES
+ None.
+
+EXTENDED DESCRIPTION
+ None.
+
+EXIT STATUS
+ The following exit values shall be returned:
+
+ 0 At least one matching process was found for each
+ pid operand, and the specified signal was suc-
+ cessfully processed for at least one matching
+ process.
+
+ >0 An error occurred.
+
+
+CONSEQUENCES OF ERRORS
+ Default.
+
+ The following sections are informative.
+
+APPLICATION USAGE
+ Process numbers can be found by using ps.
+
+ The job control job ID notation is not required to work
+ as expected when kill is operating in its own utility
+ execution environment. In either of the following exam-
+ ples:
+
+
+ nohup kill %1 &
+ system("kill %1");
+
+ the kill operates in a different environment and does
+ not share the shell's understanding of job numbers.
+
+EXAMPLES
+ Any of the commands:
+
+
+ kill -9 100 -165
+ kill -s kill 100 -165
+ kill -s KILL 100 -165
+
+ sends the SIGKILL signal to the process whose process ID
+ is 100 and to all processes whose process group ID is
+ 165, assuming the sending process has permission to send
+ that signal to the specified processes, and that they
+ exist.
+
+ The System Interfaces volume of IEEE Std 1003.1-2001 and
+ this volume of IEEE Std 1003.1-2001 do not require spe-
+ cific signal numbers for any signal_names. Even the -
+ signal_number option provides symbolic (although
+ numeric) names for signals. If a process is terminated
+ by a signal, its exit status indicates the signal that
+ killed it, but the exact values are not specified. The
+ kill -l option, however, can be used to map decimal sig-
+ nal numbers and exit status values into the name of a
+ signal. The following example reports the status of a
+ terminated job:
+
+
+ job
+ stat=$?
+ if [ $stat -eq 0 ]
+ then
+ echo job completed successfully.
+ elif [ $stat -gt 128 ]
+ then
+ echo job terminated by signal SIG$(kill -l $stat).
+ else
+ echo job terminated with error code $stat.
+ fi
+
+ To send the default signal to a process group (say 123),
+ an application should use a command similar to one of
+ the following:
+
+
+ kill -TERM -123
+ kill -- -123
+
+RATIONALE
+ The -l option originated from the C shell, and is also
+ implemented in the KornShell. The C shell output can
+ consist of multiple output lines because the signal
+ names do not always fit on a single line on some termi-
+ nal screens. The KornShell output also included the
+ implementation-defined signal numbers and was considered
+ by the standard developers to be too difficult for
+ scripts to parse conveniently. The specified output for-
+ mat is intended not only to accommodate the historical C
+ shell output, but also to permit an entirely vertical or
+ entirely horizontal listing on systems for which this is
+ appropriate.
+
+ An early proposal invented the name SIGNULL as a sig-
+ nal_name for signal 0 (used by the System Interfaces
+ volume of IEEE Std 1003.1-2001 to test for the existence
+ of a process without sending it a signal). Since the
+ signal_name 0 can be used in this case unambiguously,
+ SIGNULL has been removed.
+
+ An early proposal also required symbolic signal_names to
+ be recognized with or without the SIG prefix. Historical
+ versions of kill have not written the SIG prefix for the
+ -l option and have not recognized the SIG prefix on sig-
+ nal_names. Since neither applications portability nor
+ ease-of-use would be improved by requiring this exten-
+ sion, it is no longer required.
+
+ To avoid an ambiguity of an initial negative number
+ argument specifying either a signal number or a process
+ group, IEEE Std 1003.1-2001 mandates that it is always
+ considered the former by implementations that support
+ the XSI option. It also requires that conforming appli-
+ cations always use the "--" options terminator argument
+ when specifying a process group, unless an option is
+ also specified.
+
+ The -s option was added in response to international
+ interest in providing some form of kill that meets the
+ Utility Syntax Guidelines.
+
+ The job control job ID notation is not required to work
+ as expected when kill is operating in its own utility
+ execution environment. In either of the following exam-
+ ples:
+
+
+ nohup kill %1 &
+ system("kill %1");
+
+ the kill operates in a different environment and does
+ not understand how the shell has managed its job num-
+ bers.
+
+FUTURE DIRECTIONS
+ None.
