ed

> The original Unix text editor.

Start ed, editing an empty document (which can be saved as a new file in the current directory):

ed

Start ed, editing an empty document, with `:` as a command prompt indicator:

ed -p :

Start ed editing an existing file (this shows the byte count of the loaded file):

ed -p : {path/to/file}

Toggle the printing of error explanations. (By default, explanations are not printed and only a `?` appears):

Add text to the current document. Mark completion by entering a period by itself in a new line:

a<Enter>{text_to_insert}<Enter>.

Print the entire document (`,` is a shortcut to the range `1,$` which covers the start to the end of the document):

,p

Write the current document to a new file (the filename can be omitted if `ed` was called with an existing file):

w {filename}

Quit ed:
