skill, snice - send a signal or report process status
SYNOPSISskill [signal] [options] expression
snice [new priority] [options] expression
DESCRIPTIONThese 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.
- -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.
