# 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
|
||||
# 2018-04-25 [Robin Gierse] - Update check via systemctl for Linux with grep to produce better output for systemctl
|
||||
# 2019-03-15 [nem / liberodark] - Add support for check all failed services in linux

# 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"
|
||||
# Exemple for check all failed services
|
||||
# $ ./check_service.sh -o linux -t "systemctl list-units --state=failed"
