NAME ed2 DESCRIPTION Substitutions are very advanced. First a simple example: s/apa/bepa/ This will substitue the 'apa' in current line to 'bepa'. If an 'p' is appended, you will also immediately see the result. 1,$s/apa/bepa/ Same, but all lines in file. Only first occurence on every line. Any character can used instead of '/': s!apa!bepa!g The 'g' specifies that all occurrences of apa on this line are changed to bepa. The pattern that are supposed to be replaced, can be a regular expression. See ed3 about that. SEE ALSO ed3(LPC)
