The commandsyntax 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. (snice +4 ...)Priority numbers range from +20 (slowest) to -20 (fastest).Negative priority numbers are restricted to administrative users..SH "GENERAL OPTIONS".TSl l l.-f	fast mode	This is not currently useful.-i	interactive use	T{You will be asked to approve each action.T}-v	verbose output	T{Display information about selected processes.T}-w	warnings enabled	This is not currently useful.-n	no action	This only displays the process ID.-V	show version	Displays version of program..TE.SH "PROCESS SELECTION OPTIONS"Selection criteria can be: terminal, user, pid, command.The options below may be used to ensure correct interpretation.Do not blame Albert for this interesting interface..TSl l.-t	The next argument is a terminal (tty or pty).-u	The next argument is a username.-p	The next argument is a process ID number.-c	The next argument is a command name..TE.SH SIGNALSThe signals listed below may be available for use with skill.When known, numbers and default behavior are shown..TSlB rB lB lBlfCW r l l.Name	Num	Action	Description.TH0	0	n/a	exit code indicates if a signal may be sentALRM	14	exitHUP	1	exitINT	2	exitKILL	9	exit	this signal may not be blockedPIPE	13	exitPOLL		exitPROF		exitTERM	15	exitUSR1		exitUSR2		exitVTALRM		exitSTKFLT		exit	may not be implementedPWR		ignore	may exit on some systemsWINCH		ignoreCHLD		ignoreURG		ignoreTSTP		stop	may interact with the shellTTIN		stop	may interact with the shellTTOU		stop	may interact with the shellSTOP		stop	this signal may not be blockedCONT		restart	continue if stopped, otherwise ignoreABRT	6	coreFPE	8	coreILL	4	coreQUIT	3	coreSEGV	11	coreTRAP	5	coreSYS		core	may not be implementedEMT		core	may not be implementedBUS		core	core dump may failXCPU		core	core dump may failXFSZ		core	core dump may fail.TE.SH EXAMPLES.TSlB lBlfCW l.Command	Description.TCsnice seti crack +7	Slow down seti and crackskill -KILL -v /dev/pts/*	Kill users on new-style PTY devicesskill -STOP viro lm davem	Stop 3 userssnice -17 root bash	Give priority to root's shell.TE.SH "SEE ALSO"killall(1) pkill(1) kill(1) renice(1) nice(1) signal(7) kill(2).SH STANDARDSNo standards apply..SH AUTHORAlbert Cahalan <albert@users.sf.net> wrote skill and snice in 1999 as areplacement for a non-free version, and is the current maintainer of theprocps collection.
