| 4 | .TH KILL 1 "14 October 1994" "Linux Utilities" "Linux Programmer's Manual" | |
| 5 | .SH NAME | |
| 6 | kill \- terminate a process | |
| 7 | .SH SYNOPSIS | |
| 8 | .BR "kill" " [ \-s signal | \-p ] " " [ -a ] " "pid ..." | |
| 9 | .br | |
| 10 | .B "kill -l [ signal ]" | |
| 11 | .SH DESCRIPTION | |
| 12 | .B kill | |
| 13 | sends the specified signal to the specified process. If no signal is | |
| 14 | specified, the TERM signal is sent. The TERM signal will kill processes | |
| 15 | which do not catch this signal. For other processes, if may be necessary | |
| 16 | to use the KILL (9) signal, since this signal cannot be caught. | |
| 17 | ||
| 18 | Most modern shells have a builtin kill function. | |
| 19 | .SH OPTIONS | |
| 20 | .TP | |
| 21 | .BR "pid ..." | |
| 22 | Specify the list of processes that | |
| 23 | .B kill | |
| 24 | should signal. Each | |
| 25 | .I pid | |
| fd6b7a7f KZ |
26 | can be one of four things. A |
| 27 | .I "process name" | |
| 28 | in which case processes called that will be signaled. | |
| 29 | .I n | |
| 30 | where | |
| 31 | .I n | |
| 32 | is larger than 0. The process with pid | |
| 33 | .I n | |
| 34 | will be signaled. | |
| 35 | .I -1 | |
| 36 | in which case all processes from MAX_INT to 2 will be signaled, | |
| 37 | as allowed by the issuing user. | |
| 38 | .I -n | |
| 39 | where | |
| 40 | .I n | |
| 41 | is larger than 1, in which case processes in process group | |
| 42 | .I n | |
| 43 | are signaled. IFF a negative argument is given the signal | |
| 44 | .I must | |
| 45 | be specified first, otherwise it will be taken as the signal to send. | |

46 | .TP |
| 47 | .BR \-s | |
| 48 | Specify the signal to send. | |
| 49 | The signal may be given as a signal name or number. | |
| 50 | .TP | |
| 51 | .BR \-p | |
| 52 | Specify that | |
| 53 | .B kill | |
| 54 | should only print the process id | |
| 55 | .I (pid) | |
| 56 | of the named process, and should not send it a signal. | |
| 57 | .TP | |
| 58 | .BR \-l | |
| 59 | Print a list of signal names. These are found in | |
| 60 | .I /usr/include/linux/signal.h | |

| 67 | Taken from BSD 4.4. The ability to translate process names to process | |
| 68 | ids was added by Salvatore Valente <svalente@mit.edu>. |
