The given command is utilizing the sudo command, which allows a user with administrative privileges to run programs or execute commands with the security privileges of another user, usually the root user.

In this case, the etckeeper command is being executed with sudo. Etckeeper is a tool used in Linux-based operating systems to track changes made to the /etc directory, where system configuration files are stored.

The commit subcommand is used to record changes made to the /etc directory into a version control system (VCS) repository. This command creates a new commit that includes the changes made to the /etc directory.

${message} is a placeholder for an argument that should be provided when executing the command. The user is expected to replace ${message} with an actual message text enclosed in quotes. The message should provide a brief description of the changes made or any other relevant information about the commit.

For example, if you want to commit changes made to the /etc directory with the message "Updated SSH configuration", the command would be:

sudo etckeeper commit "Updated SSH configuration"

Remember to use this command responsibly, as it can make permanent changes to your system's configuration.
