xcaddy:tldr:7c7d7
This command is invoking the "xcaddy" tool to run a Caddy server with a specific configuration file.
Here's a breakdown of each component:
-
"xcaddy" is the name of the command-line tool that is being executed. It is a utility tool used for building Caddy servers with custom modules and configurations.
-
"run" is an argument or subcommand given to "xcaddy". It instructs the tool to run the Caddy server.
-
"--config" is another argument passed to "xcaddy". It specifies that the following value is the path or filename of the Caddy configuration file.
-
"${filename}" is a placeholder for an actual filename. It means the value should be substituted with the actual filename you want to use as the Caddy configuration file.
So, when you execute this command, the "xcaddy" tool will run a Caddy server using the specified configuration file (which should be provided as the value of the "${filename}" variable).
