ed -p :

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

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

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

w [filename]

- Quit ed:
