The command "pacdiff --sudo" is a command-line instruction that is commonly used in Linux systems, specifically the Arch Linux distribution or its derivatives.

The "pacdiff" command is used to compare and merge configuration files that have been changed during a package update. It helps to identify the differences between the new and old configuration files and allows the user to manually merge the changes.

The "--sudo" option is an argument that allows the execution of the pacdiff command with elevated privileges using the "sudo" command. "sudo" stands for "superuser do" and is a command that allows users to perform tasks as the root or administrator user.

By running "pacdiff --sudo", you ensure that the pacdiff command will have the necessary permissions to modify and merge any configuration files that require administrative access. This is particularly useful when dealing with system-level configuration files that are owned by the root user.
