    By not using a GUI. I don't have any clue what your actual question might be?

    The same way as an OS that does have a GUI... but they don't run the GUI program... this is an odd question... any more context?

So, before GUI you had typing at the command line, writing, compiling and running programs that would expect the input (in a particular form string of numbers etc) then run and give output on the screen - again text based.

Prior to that there were systems that had an input on punched card and the output would require decoding.

Research early computers and interfaces.
