| .SH DESCRIPTION |
| The default signal for kill is TERM. Use -l or -L to list available signals. |
| Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0. |
| Alternate signals may be specified in three ways: -9 -SIGKILL -KILL. |
| Negative PID values may be used to choose whole process groups; see the |
| PGID column in ps command output. A PID of -1 is special; it indicates |
| all processes except the kill process itself and init. |

| the conflict. |

| .SH STANDARDS |

| |
| .SH AUTHOR |
| Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a |
| bsdutils one that was not standards compliant. The util-linux one might |
| also work correctly. |
