# 2015-03-09 [Pascal Hegy] - Change USER variable to USERNAME to avoid the use and confusion with the USER env variable
# 2017-08-30 [Roberto Leibman] - Reordered checks to make sure dead and inactive get checked first

# Examples:

# 1.) List services for osx
# $ ./check_service.sh -l -o osx
#
# 2.) Check status of SSH service on a linux machine
# $ ./check_service.sh -o linux -s sshd

# 3.) Manually select service management tool and service
# $ ./check_service.sh -o linux -t "service rsyslog status"

# Nagios Exit Codes

Check status of system services for Linux, FreeBSD, OSX, and AIX.

     Options:
        -s <service>    Specify service name
        -l              List services
        -o <os>         OS type, "linux/osx/freebsd/aix"
        -u <user>       User if you need to ``sudo -u'' for launchctl (def: nagios, linux and osx only)
        -t <tool>       Manually specify service management tool (def: autodetect) with status and service
                        e.g. ``-t "service nagios status"''
