.SH DESCRIPTION
|
|
These tools are obsolete and unportable. The command syntax is
|
|
poorly defined. Consider using the killall, pkill, and pgrep
|
|
commands instead.
|
|
.PP
|
|
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.
|
|
.PP
|
|
The default priority for snice is +4. Priority numbers range from
|
|
+20 (slowest) to \-20 (fastest). Negative priority numbers are
|
|
restricted to administrative users.
