In vi, how can I perform a global search and replace?

To perform a global search and replace in vi, use the search and replace command in command mode:

The % is a shortcut that tells vi to search all lines of the file for search_string and change it to replacement_string. The global ( g ) flag at the end of the command tells vi to continue searching for other occurrences of search_string . To confirm each replacement, add the confirm ( c ) flag after the global flag.
