xauth:tldr:04b97

The "xauth remove ${display_name}" command is used to remove the X authority (xauth) entries for a specific display.

Here's how it works:

1. "xauth" is a command-line tool used for managing X Window System's security, specifically the authentication of X client connections.
2. "remove" is an option or subcommand of the "xauth" command, which signifies that we want to remove the specified X authority entry.
3. "${display_name}" is a placeholder or variable representing the name or identifier of the display for which you want to remove the X authority entry. The display name usually follows the format "hostname:display_number.screen_number".

For example, if you have a display with the name "localhost:0.0" and want to remove its X authority entry, you would use the command "xauth remove localhost:0.0".
