The ed man page starts famously with "The ed utility is the standard text editor." It was the standard text editor in the first Unix version and continued to be the main interactive text editor until the appearance of vi.
No one uses this editor as a standalone anymore, but most of the power of vi is due to the ed (or ex) commands.
How to run ed
