rc-service:tldr:d8ebe
This command is used in certain Linux distributions (such as Gentoo) to manage services through the runlevel scripts.
Let's break down the command:
-
sudo
: This is a command that allows users to run programs or commands with the security privileges of another user, typically the superuser (root). It prompts the user for their password before executing the command. -
rc-service
: This is the main command used to manage services in Gentoo Linux. It is followed by the service name and the command to be executed. -
${service_name}
: This is a placeholder that needs to be replaced with the actual name of the service you want to manage. For example, if you want to start or stop the Apache web server service, you would replace${service_name}
withapache2
. -
${command_name}
: This is another placeholder that needs to be replaced with the specific command you want to execute on the service. For example, if you want to start the service, you would replace${command_name}
withstart
. Other common commands includestop
,restart
,status
, and more.
When you replace the placeholders with the actual service and command names, the command becomes sudo rc-service apache2 start
, which would start the Apache web server service with root privileges.
