Manual:Edit.php

Edit an article from the command line

Usage: php edit.php [options...]

Options: -u Username -s Edit summary -m Minor edit -b Bot (hidden) edit -a Enable autosummary --no-rc Do not show the change in recent changes

If the specified user does not exist, it will be created. If no username has been provided, the edit will be attributed to user "Maintenance script", created if needed. The text for the edit will be read from stdin.

Examples
php edit.php -s "Quick edit" -m Page_I_want_to_edit < file_containing_wikitext

The above will edit the page  (marking the edit minor) so it contains the contents of the file file_containing_wikitext using the edit summary Quick edit. php "page_title" | sed -e 's/\bfoo\b/bar/g' | php edit.php "page_title"

The above will take the text of the page  from your wiki, replace  every occurrence of the word foo with the word bar, and save the result back to the page. You can do many complex text transformations of page text this way; see your unix manual's entry for sed.
