* * * * * wget -O - http://yoursite.com/tasks.php >/dev/null 2>&1
That should work for you. Just have a wget
script that loads the page.
Using -O -
means that the output of the web request will be sent to STDOUT (standard output)
by adding >/dev/null
we instruct standard output to be redirect to a black hole.
by adding 2>&1
we instruct STDERR (errors) to also be sent to STDOUT, and thus all output will be sent to a blackhole. (so it will load the website, but never write a file anywhere)
