The command sudo
is used to run a command with superuser (root) privileges. It allows the user to execute commands that require elevated permissions.
sv
is a command-line utility in Unix-like operating systems, often used for managing services. It is used to control services supervised by a runit service supervisor. Runit is a service supervision tool that helps manage and supervise daemons, ensuring they stay alive and are automatically restarted if they fail.
The down
argument is used with sv
to stop or halt a service that is currently running or supervised by runit.
${path-to-service}
is a placeholder representing the actual path to the service you want to stop or halt. You need to replace ${path-to-service}
with the correct path to the service, for example /etc/service/my-service
or /run/service/my-service
.
When executed, the sudo sv down ${path-to-service}
command will attempt to stop or halt the specified service using the runit service supervisor, with the necessary root privileges.
