The command "whatis" is used in Unix-like operating systems to provide a short description of a given command or program. The ${command} is a placeholder, and you should replace it with the actual command you want to look up. For example, if you want to find the description of the "ls" command, you would enter: whatis ls The output may provide a brief summary of the command's functionality and usage. It is a quick way to get a basic understanding of what a particular command does without needing to access the full manual page.
