| 23 | +# <http://xyz.com/wp-content/update-feeds.php>, where `http://xyz.com/` is | |
| 24 | +# replaced by the URI to your installation of WordPress. Log in as any | |

| 28 | +# update-feeds.php locally: | |

| 30 | +# cd /path/to/wordpress/wp-content ; php update-feeds.php | |
| 26 | 31 | # |
| 27 | -# curl http://xyz.com/wp-content/update-feeds.php?shibboleth=foo | |
| 32 | +# where `/path/to/wordpress` is replaced by the filesystem path to your | |
| 33 | +# installation of WordPress; or, if you don't have, or don't want to use, | |
| 34 | +# command-line PHP, you can send an HTTP POST request to the appropriate | |
| 35 | +# URI: | |
| 28 | 36 | # |
| 37 | +# curl --user user:pass http://xyz.com/wp-content/update-feeds.php -d update=quiet | |
| 38 | +# | |
| 39 | +# `user` and `pass` should be replaced by the username and password of | |
| 40 | +# a user in your WordPress database (you can create a dummy user for | |
| 41 | +# updates if you want; that's what I do). `http://xyz.com/` should be | |
| 42 | +# replaced by the URI to your installation of WordPress. | |
| 43 | +# | |
| 44 | +# Don't be afraid to run this cron job frequently. FeedWordPress staggers | |
| 45 | +# updates over time rather than checking all of the feeds every time the | |
| 46 | +# cron job runs, so even if the cron job runs every 10 minutes, each feed | |
| 47 | +# will, on average only be polled for updates once an hour or so (or less | |
| 48 | +# frequently if the feed author requests less frequent updates using | |
| 49 | +# the RSS <ttl> element or the syndication module elements). | |
