<H2>DESCRIPTION</H2>
|
|
|
|
These tools are obsolete and unportable. The command syntax is
|
|
poorly defined. Consider using the killall, pkill, and pgrep
|
|
commands instead.
|
|
<P>
|
|
|
|
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.
|
|
<P>
|
|
|
|
The default priority for snice is +4. Priority numbers range from
|
|
+20 (slowest) to -20 (fastest). Negative priority numbers are
|
|
restricted to administrative users.
