That's a file not a URL - just perform a wget in the url – Ballinger

Based on the comments try

*/5 * * * * wget http://example.com/check

This answer still seems to be getting a few hits so I thought I'd add a link to a new page I stumbled across which may help create cron commands: https://crontab.guru

wget will create temporary files uses like that – Toshikotoss

Edited to ensure temporary file not created (hope it's accepted, but JiC) */5 * * * * wget -qO- http://example.com/check &> /dev/null – Magically

I would do */5 * * * * wget example.com/check --delete-after to make sure there are no temporary files – Function

And don't forget to call sudo service cron reload after saving the crontab file ;) – Denudate

Use cURL:

*/5 * * * * curl http://example.com/check/

Just a note, you should run curl without output or progress by piping to /dev/null like so. */5 * * * * curl -s http://example.com/check/ > /dev/null – Magically

If any error occured on that, you could try double quotes around URL. like that <code> curl -s "example.com/check" > /dev/null </code> – Diplocardiac

Answer 3

The other advantage of using curl is that you also can keep the HTTP way of sending parameters to your script if you need to, by using $_GET, $_POST etc like this:

*/5 * * * * curl --request GET 'http://exemple.com/path/check.php?param1=1&param2=2'

Here is an example of the wget script in action:

wget -q -O /dev/null "http://example.com/cronjob.php" > /dev/null 2>&1

Using -O parameter like the above means that the output of the web request will be sent to STDOUT (standard output).

And the >/dev/null 2>&1 will instruct standard output to be redirected to a black hole. So no message from the executing program is returned to the screen.

Answer 5

To run a url, you need a program to get that url. You can try wget or curl. See manuals for available options.

Nothing worked for me on my linux hosting. The only possible commands they provide are:

/usr/local/bin/php absolute/path/to/cron/script

and

/usr/local/bin/ea-php56 absolute/domain_path/path/to/cron/script 

This is how I made it to work: 1. I created simple test.php file with the following content:

echo file_get_contents('http://example.com/check/');

2. I set the cronjob with the option server gived me using absolute inner path :)

/usr/local/bin/php absolute/path/to/public_html/test.php
