# calling preload from Linux cron?

 * For some time it has bothered me that I cannot set a precise preload time within
   the plugin (i.e. so that preloaded cache is rebuilt at say, 1:00am every single
   day). Even setting the expiration to 1420 does not achieve a 1:00 refresh as 
   it will be 1420 minutes _after_ the previous cache concluded, thus causing the
   following preload to commence before 1:00 or after 1:00, depending on the server
   load at the time the previous cache was performed.
 * So I thought I’d try to create a Linux cron trigger, but no success. Can someone
   please explain why
 * `curl -m 10 -s -S https://www.voxclamantisindeserto.us/wp-cron.php?doing_wp_cron
   1>/dev/null`
 * will trigger all scheduled tasks, but neither
 * `curl -m 10 -s -S https://www.voxclamantisindeserto.us/wp-cron.php?wp_cron_preload_cache
   1>/dev/null`
 * nor
 * `curl -m 10 -s -S https://www.voxclamantisindeserto.us/wp-cron.php?wp_cache_full_preload_hook
   1>/dev/null`
 * nor
 * `curl -m 10 -s -S https://www.voxclamantisindeserto.us/wp-cron.php?doing_wp_cron
   =wp_cron_preload_cache 1>/dev/null`
 * nor
 * `curl -m 10 -s -S https://www.voxclamantisindeserto.us/wp-cron.php?doing_wp_cron
   =wp_cache_full_preload_hook 1>/dev/null`
 * will trigger super cache to commence preloading?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcalling-preload-from-linux-cron%2F%3Foutput_format%3Dmd&locale=en_US)
