loadkeys:tldr:5b70c

The command loadkeys is used to load keyboard mapping tables and functionally remap keys in Linux systems.

Let's break down the different parts of the command:

• loadkeys is the actual executable command to load keyboard layouts and mappings.
• --console is an option or parameter that specifies the console device to load the keymaps for. The console device is typically /dev/ttyN, where N refers to the number of the terminal (e.g., /dev/tty1 for the first virtual console).
• ${-dev-ttyN} is not a valid syntax, as it seems to be a mix of options and command substitution using ${}. It should likely be --dev=/dev/ttyN to specify the console device explicitly.
• ${-filename} is again not a valid syntax and seems to be using command substitution incorrectly. It should likely be --file=filename, where filename should be replaced with the actual path of the keymap file to load.

In summary, the corrected command would look something like this:

loadkeys --console --dev=/dev/ttyN --file=filename

This corrected command would be used to load a specified keymap file on a specific console device in Linux.
