SKILL(1) User Commands SKILL(1)
skill, snice - send a signal or report process status
skill [signal-option] [other-option ...] expression
snice [new-priority] [option ...] expression
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.
-f, --fast
Fast mode. This option has not been implemented.
-i, --interactive
Interactive use. You will be asked to approve each
action.
-l, --list
List all signal names.
-L, --table
List all signal names in a nice table.
-n, --no-action
No action; perform a simulation of events that would occur
but do not actually change the system.
-v, --verbose
Verbose; explain what is being done.
-w, --warnings
Enable warnings. This option has not been implemented.
-h, --help
Display help text and exit.
-V, --version
Display version information.
Selection criteria can be: terminal, user, pid, command. The
options below may be used to ensure correct interpretation.
-t, --tty tty
The next expression is a terminal (tty or pty).
-u, --user user
The next expression is a username.
-p, --pid pid
The next expression is a process ID number.
-c, --command command
The next expression is a command name.
--ns pid
Match the processes that belong to the same namespace as
pid.
--nslist ns,...
list which namespaces will be considered for the --ns
option. Available namespaces: ipc, mnt, net, pid, user,
uts.
The behavior of signals is explained in signal(7) manual page.
snice -c seti -c crack +7
+Slow down seti and crack commands.
skill -KILL -t /dev/pts/*
Kill users on PTY devices.
skill -STOP -u viro -u lm -u davem
Stop three users.
kill(1), kill(2), killall(1), nice(1), pkill(1), renice(1),
signal(7)
No standards apply.
Albert Cahalan ⟨albert@users.sf.net⟩ wrote skill and snice in
1999 as a replacement for a non-free version.
