I'm newbie in cron commands and I need help.

I have a script on

Whats is command for cron to run this URL every 5 minutes?

I tried

*/5 * * * * /home/test/check.php

But I want to run URL not relative script address. How to do it?



Based on the comments try

*/5 * * * * wget

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:

In a crontab file, the fields are:

  • minute of the hour.
  • hour of the day.
  • day of the month.
  • month of the year.
  • day of the week.


10 * * * * blah

means execute blah at 10 minutes past every hour.

If you want every five minutes, use either:

*/5 * * * * blah

meaning every minute but only every fifth one, or:

0,5,10,15,20,25,30,35,40,45,50,55 * * * * blah

for older cron executables that don't understand the */x notation.

If it still seems to be not working after that, change the command to something like:

date >>/tmp/debug_cron_pax.txt

and monitor that file to ensure something's being written every five minutes. If so, there's something wrong with your PHP scripts. If not, there's something wrong with your cron daemon.

There are no problems running a PHP script as a cron job. What you need to do is provide the full path in the filesystem to the script file, and use the command php to tell Linux what program to run the file with.


*/5 * * * * php /var/www/vhosts/statistikk/cron/getLastArticleFromIntranet.cron.php >> /var/www/vhosts/statistikk/cron/LOG.txt 2> /dev/null

This script will run every 5 minutes, all days of the week. Whatever the PHP-script echoes / prints out, will be stored to the LOG.txt file so that I can monitor the scripts events.

Try running just the command in your shell before putting it in the cronjobs to make sure it works.

However, you say that you normally call this script with a AJAX call. This will not be possible to do with a cronjob. I assume you use AJAX to pass along some $_POST-elements that the script needs. So what you have to do is either adapt the script to allow $argv parameters as well, and add them to the crontab job, or simply make a script which does not need any given parameters before it runs.

If you are going to adapt your script to support $argv parameters, follow the answer already existing on about adding parameters to the job:

How to run a php url with parameters in cron tab


I'd just like to add to my answer as from the answer below. To edit you crontab jobs in Linux you can simply use the command crontab -e.

This is the description of each required param that needs to be filled.

*     *     *   *    *        command to be executed
-     -     -   -    -
|     |     |   |    |
|     |     |   |    +----- day of week (0 - 6) (Sunday=0)
|     |     |   +------- month (1 - 12)
|     |     +--------- day of        month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59)

Looks like that you copied your full php.ini from your windows machine (probably the dev environment) up to a remote server which is running some linux distribution.

The extensions listed in your xampp provided php.ini won't work this way over there. If you are certain that you want to copy the whole php.ini from your dev machine, (you most likely won't need that) you will probably have to remove or edit the extension= lines to fit the environment (They most likely should end with .so at least and have a different path). Checking every path related setting would be wise too.

(Using full paths in every extension= line is foolish since there's extension_dir)

You can use push Notification, or rawnotification dependent on how much data is needed to be send. And when the app is in foreground you can accomplish what you want with a timer? But using background tasks is not possible.
