The command "doas -C ${config_file} ${command}" is used to execute a specific command using the doas utility with a specific configuration file.

Here is an explanation of each component of the command:

• "doas": doas is a sudo-like utility that allows users to run commands as a different user, typically as the root user, after providing proper authentication.
• "-C ${config_file}": This option specifies the configuration file to be used by doas. The ${config_file} placeholder represents the path to the actual configuration file. The configuration file defines the settings and rules for using doas, such as which users are allowed to execute commands and what commands they are permitted to run.
• "${command}": This represents the command that you want to execute using doas. It can be any valid command-line instruction or script.

In summary, the "doas -C ${config_file} ${command}" command allows you to run a specific command with elevated privileges as defined by the configuration file specified.
