In the Beginning there was the Command Line[edit]

UNIX Philosophy[edit]

This is the Unix philosophy: Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface. - Doug McIlroy 1994

  • This is the true power of the command line, you are no longer limited but what is implemented by a single program, and can use many smaller tools to get exactly what you want!
