NAME


skill, snice - send a signal or report process status

SYNOPSIS


skill [signal] [options] expression
snice [new priority] [options] expression

DESCRIPTION


These tools are obsolete and unportable. The command syntax is poorly defined. Consider
using the killall, pkill, and pgrep commands instead.

The default signal for skill 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.

The default priority for snice is +4. Priority numbers range from +20 (slowest) to -20
(fastest). Negative priority numbers are restricted to administrative users.

-l, --list

-L, --table

-n, --no-action
No action; perform a simulation of events that would occur but do not actually

-w, --warnings
Enable warnings. This option has not been implemented.

-h, --help
Display help text and exit.
