scutil:tldr:c96d2

This command is used in macOS to change the computer's name using the scutil (System Configuration Utility) command-line tool. Let's break down the components of the command:

• sudo: It stands for "superuser do" and is used to execute the given command with administrative privileges. It requests the user's password if necessary.

• scutil: It is a command-line tool provided by macOS for querying and manipulating various system configuration settings.

• --set: It is an option used with the scutil command to indicate that we want to set a specific value.

• ComputerName: It is a system configuration setting that represents the name of the computer or host.

• ${computer_name}: This is a variable denoted by ${} that holds the desired computer name. It should be replaced with the actual name desired for the computer. For example, if you want to set the computer name as "MyMac", you would replace ${computer_name} with MyMac.

Therefore, when you execute sudo scutil --set ComputerName ${computer_name}, it will set the computer's name to the value stored in ${computer_name} by using administrative privileges.
