SKILL(1)							   User Commands							  SKILL(1)

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.

OPTIONS

       -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.

PROCESS SELECTION OPTIONS

       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.

SIGNALS

       The behavior of signals is explained in signal(7) manual page.

EXAMPLES

       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.

SEE ALSO

       kill(1), kill(2), killall(1), nice(1), pkill(1), renice(1), signal(7)

STANDARDS

       No standards apply.

AUTHOR

       Albert Cahalan <albert@users.sf.net> wrote skill and snice in 1999 as a replacement for a non-free version.
