The command "dict -D" is used to access the dictionary in the terminal on Unix-like systems.

The "dict" command is a client program that connects to a dictionary server to look up word definitions, synonyms, antonyms, translations, and related information. The "-D" option is used to launch the dictionary in interactive mode, allowing the user to enter multiple queries without exiting the dictionary program.

Once you enter the "dict -D" command in the terminal, you will be prompted to enter a word or a phrase for which you want to get the dictionary information. After entering the query, the dictionary server will provide the relevant information, such as the definition of the word, synonyms, or translations if available. You can then enter more words or phrases without exiting the program until you decide to exit by typing a specific command or key combination (usually Ctrl+C).
