In Linux, the hyphen or dash (-) is the character that identifies a command option or "switch". It is often used before a single letter option or to indicate a short form of a command. For example, the "ls" command has options such as "-l" (long format) and "-a" (list all files, including hidden files) that are used with a hyphen before the letter. Some commands may also use double hyphens (--), which are used before longer options or to allow options with multiple words, such as "--exclude pattern" in the "grep" command.
