Manual:GetText.php

getText.php is a maintenance script that outputs content of a given page (wikitext) to stdout. It could be used for scripting, for example:

php getText.php "page title" | sed -e '...' | php edit.php "page title"

The only parameter, in addition to standard ones, is page title. If it contains whitespace, it should be enclosed in double quotes ("), as shown in example.
