Use the .edit command to search and replace text strings in one or more files. The .edit command replaces the first instance of the string (search_expression) on each and every line in each file specified.

The .edit command implements standard POSIX regular expressions for matching and replacement, including the use of () substring selection and \N substitution in the replacement pattern.
