skill, snice - send a signal or report process status


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


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

   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

   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)

   replacement for a non-free version.
