# This script controls services that are not registered as system
# services which respond to calls from /sbin/chkconfig or
# /sbin/services.
#
# USAGE:
#	service-control service action
# Where:
#	service is any named service listed in KNOWN_SERVICES below, and
#		for which you have coded the actions in main() below.
#	action is any of those listed in KNOWN_ACTIONS below, and for which
#		code has been written in main() below.
#
# EXAMPLES:
#	service-control popauth restart
#	service-control popauth status
#
# Script Version:
#	1.0
# Original Author:
#	William Kimball, Jr. <wwopensource at kimballstuff dot com>

# OPTIONS

#---------------------------------------------------------------------#
# This set of _PATH options specify the absolute paths to some programs
# which this script relies on.  The recommended values come from
# RHEL4/CentOS4 systems and may not fit your site's configuration.
# While is is possible, and generally okay, to specify only a program
# name without any pathing information, these options help in cases
# where this script runs in an automated context (cron, at, etc.)
# without an appropriate $PATH environment variable.
# Power User Note:  If you put these values in quotes, then you can
# also specify additional options to these commands, which will precede
# the arguments passed by this script.  Doing this isn't recommended as
# you will alter the expected behavior of this script beyond the intent
# of its author, but the possibility is available to you.
#
# Recommended values:
# ECHO_PATH=/bin/echo
# PRINTF_PATH=/usr/bin/printf
# TR_PATH=/usr/bin/tr
# CAT_PATH=/bin/cat
# SLEEP_PATH=/bin/sleep
# KILL_PATH=/bin/kill
#---------------------------------------------------------------------#
ECHO_PATH=/bin/echo
PRINTF_PATH=/usr/bin/printf
TR_PATH=/usr/bin/tr
CAT_PATH=/bin/cat
SLEEP_PATH=/bin/sleep
KILL_PATH=/bin/kill
