1kill [ -s signal name | -n signal number | -sig ] job ... 2 - - 3kill -l [ sig ... ] 4 Sends either SIGTERM or the specified signal to the given jobs 5 or processes. Signals are given by number or by names, with or 6 without the `SIG' prefix. If the signal being sent is not 7 `KILL' or `CONT', then the job will be sent a `CONT' signal if 8 it is stopped. The argument job can be the process ID of a job 9 not in the job list. In the second form, kill -l, if sig is not 10 specified the signal names are listed. Otherwise, for each sig 11 that is a name, the corresponding signal number is listed. For 12 each sig that is a signal number or a number representing the 13 exit status of a process which was terminated or stopped by a 14 signal the name of the signal is printed. 15 16 On some systems, alternative signal names are allowed for a few 17 signals. Typical examples are SIGCHLD and SIGCLD or SIGPOLL and 18 SIGIO, assuming they correspond to the same signal number. kill 19 -l will only list the preferred form, however kill -l alt will 20 show if the alternative form corresponds to a signal number. 21 For example, under Linux kill -l IO and kill -l POLL both output 22 29, hence kill -IO and kill -POLL have the same effect. 23 24 Many systems will allow process IDs to be negative to kill a 25 process group or zero to kill the current process group. 26
