rc-service:tldr:64d02
The given command sudo rc-service --dry-run ${service_name} ${command_name}
is a command-line instruction to interact with the rc-service
command in Unix-like operating systems.
Here is an explanation of each component of the command:
-
sudo
: It is a command used in Unix-like systems to run subsequent commands with elevated privileges.sudo
stands for "Super User Do," and using this command usually requires authentication, such as providing the system password. -
rc-service
: It is a command used in Gentoo Linux and some other related distributions to control services on the system. It allows starting, stopping, restarting, or checking status of services. -
--dry-run
: It is an option specific to therc-service
command. When used, it doesn't perform the actual actions but simulates them. It is helpful to check the expected outcome or verify the correct execution of a command without making any changes to the system. -
${service_name}
: It is a placeholder representing the name of the service to be acted upon. You need to replace${service_name}
with the actual name of the service you want to target. For example, if you want to check the dry run of the service callednginx
, you would replace${service_name}
withnginx
. -
${command_name}
: It is another placeholder representing the specific action to be performed on the service. You need to substitute${command_name}
with the desired action, such asstart
,stop
,restart
,status
, etc. The available actions depend on the service management implementation for your distribution.
