written by Admin

Problem

Over a serial console or in embedded devices I cannot edit text files using vi or emacs, but only using ed. It´s a bit obscure, how can I do?

Solution

First start editing session:

#ed filename

To print file contents type ,p
To print and point to next line type +
To print and point to previous line type -
To delete current line type d
To insert text in current position type a and conclude insertion with a dot alone on a line
To search for a text type /text/
To replace some text type s/search/replace/
To save type w
...then exit with q
