Dear, I broke my head and googled for a long time, and did not find a fully working example. This cron task, when testing, seemed to work, when it finally got into the system, an error crashes.
30 */12 * * * /usr/bin/wget http://site.net/res/add.php?cs=2>>/home/www/site/log/loggraber.txt
Here is the error:
CRON[17904]: (CRON) error (grandchild #17905 failed with exit status 2)
The essence of the crown: at the specified time, this URL was called with the parameter, well, and I throw the execution log into the site logs.
