| 13 | The kill utility sends a signal to the processes specified by the pid |
| 14 | operand(s). |
| 15 | |
| 16 | Only the super-user may send signals to other users' processes. |
| 17 | |
| 18 | The options are as follows: |
| 19 | |
| 20 | -\b-s\bs _\bs_\bi_\bg_\bn_\ba_\bl_\b__\bn_\ba_\bm_\be |
| 21 | A symbolic signal name specifying the signal to be sent instead |
| 22 | of the default TERM. |
| 23 | |
| 24 | -\b-l\bl [_\be_\bx_\bi_\bt_\b__\bs_\bt_\ba_\bt_\bu_\bs] |
| 25 | If no operand is given, list the signal names; otherwise, write |
| 26 | the signal name corresponding to _\be_\bx_\bi_\bt_\b__\bs_\bt_\ba_\bt_\bu_\bs. |
| 27 | |
| 28 | -\b-s\bsi\big\bgn\bna\bal\bl_\b_n\bna\bam\bme\be |
| 29 | A symbolic signal name specifying the signal to be sent instead |
| 30 | of the default TERM. |
| 31 | |
| 32 | -\b-s\bsi\big\bgn\bna\bal\bl_\b_n\bnu\bum\bmb\bbe\ber\br |
| 33 | A non-negative decimal integer, specifying the signal to be sent |
| 34 | instead of the default TERM. |
| 35 | |
| 36 | The following pids have special meanings: |
| 37 | -1 If superuser, broadcast the signal to all processes; otherwise |
| 38 | broadcast to all processes belonging to the user. |
| 39 | |
| 40 | Some of the more commonly used signals: |
| 41 | 1 HUP (hang up) |
| 42 | 2 INT (interrupt) |
| 43 | 3 QUIT (quit) |
| 44 | 6 ABRT (abort) |
| 45 | 9 KILL (non-catchable, non-ignorable kill) |
| 46 | 14 ALRM (alarm clock) |
| 47 | 15 TERM (software termination signal) |
| 48 | |
| 49 | K\bKi\bil\bll\bl is a built-in to csh(1); it allows job specifiers of the form |
| 50 | ``%...'' as arguments so process id's are not as often used as k\bki\bil\bll\bl argu- |
| 51 | ments. See csh(1) for details. |

| 57 | The k\bki\bil\bll\bl function is expected to be IEEE Std1003.2 (``POSIX'') compati- |
| 58 | ble. |

| 64 | A replacement for the command ``kill 0'' for csh(1) users should be pro- |
| 65 | vided. |
