Manage services in systemd, openRC and runit

systemd

• list all services: systemctl list-unit-files
• list running services status: systemctl list-units
• list failed services: systemctl --failed
• list available services: systemctl --all
• start a service: systemctl start [SERVICE_NAME]
• stop a service: systemctl stop [SERVICE_NAME]
• restart a service: systemctl restart [SERVICE_NAME]
• get the status of a service: systemctl status [SERVICE_NAME]
• enable a service: systemctl enable [SERVICE_NAME]
• disable a service: systemctl disable [SERVICE_NAME]

openRC

• list services: rc-status
• list failed services: rc-status --crashed
• list available services: rc-update -v show or ls /etc/init.d/
• start a service: rc-service [SERVICE_NAME] start or service [SERVICE_NAME] start or /etc/init.d/[SERVICE_NAME] start
• stop a service: rc-service [SERVICE_NAME] stop or service [SERVICE_NAME] stop or /etc/init.d/[SERVICE_NAME] stop
• restart a service: rc-service [SERVICE_NAME] restart or service [SERVICE_NAME] restart or /etc/init.d/[SERVICE_NAME] restart
• get the status of a service: rc-service [SERVICE_NAME] status or service [SERVICE_NAME] status or /etc/init.d/[SERVICE_NAME] status
• enable a service: rc-update add [SERVICE_NAME]
• disable a service: rc-update del [SERVICE_NAME]

runit ❤️

note, if you're an Artix user, available services are in /etc/runit/sv directory and the enabled services are in /run/runit/service directory

• list all available services: ls /etc/sv
• list all enabled services: ls /var/service/
• start a service: sv up [SERVICE_NAME] or sv u [SERVICE_NAME]
• stop a service: sv down [SERVICE_NAME] or sv d [SERVICE_NAME]
• restart a service: sv restart [SERVICE_NAME] or sv t [SERVICE_NAME]
• get the status of a service: sv status [SERVICE_NAME] or sv s [SERVICE_NAME]
• get the current status of all enabled services: sv status /var/service/*
• enable a service: ln -s /etc/sv/[SERVICE_NAME] /var/service
• disable a service: rm /var/service/[SERVICE_NAME]

Very nice, thank you

Please, use standard UNIX man page syntax conventions. All mandatory parameters should be enclosed in angle brackets (<>) and optional ones in square brackets ([]). Example for OpenRC, where service is mandatory and runlevel optional (which defaults to, well, runlevel default):

• enable service: rc-update add <service> [runlevel]

I can't run any of the openRC commands beginning with service , e..g, service [SERVICE_NAME] start .
