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
