Installs a robots.txt file that blocks all indexing for both PHP and node/stagecoach sites found on the server. Usually run as a cron job.
A robots.txt file that disallows indexing is installed in /var/www/*/web and /opt/stagecoach/apps/*/current/public.
We use this on staging servers where a more complete lockdown, such as restricting access by password or IP address, is not required and we simply want to avoid obsolete content being found in Google.
Usage
Run it as a user with appropriate privileges to create robots.txt files in the above-mentioned places:
robot-apocalypse
Warnings
This obviously does not instantly purge results from Google. It takes time for search engines to re-crawl a site. Only well-behaved search engine spiders pay attention to robots.txt files.
If what you want is security, this is the wrong tool for your needs. You should set a password for access to your content, or lock it down by other means.
If you don't want a firm "go away, no indexing" rule for every site... don't run this.
Options
Add --verbose to print the path to each folder in which a robots.txt file is created.
