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, --ttytty
The next expression is a terminal (tty or pty).
- -u, --useruser
The next expression is a username.
- -p, --pidpid
The next expression is a process ID number.
- -c, --commandcommand
The next expression is a command name.
- --nspid
Match the processes that belong to the same namespace as pid.
- --nslistns,...
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.
