cls (for clear screen) is a command used by the command line interpreters COMMAND.COM and cmd.exe on DOS, OS/2 and Microsoft Windows operating systems to clear the screen or console window of commands and any output generated by them. It does not clear the user's history of commands, however. In other environments, such as Linux and Unix, the same functionality is provided by the "clear" command. [Wikipedia]
