Crontab please help

I need to run php -q /home/myweb/public_html/check.php every 85 minutes (1 hour 25 minutes) so i added
*/25 */1 * * * php -q /home/myweb/public_html/check.php

but it run on minute 25 and 50 every hours (based on /var/log/cron).

please help

 

Set a cron to run every 1 minute: * * * * * /home/myweb/script.sh

Create a shell script (note set the execute permission on this) script.sh:

#!/bin/bash
reftime=$(date -u -d "20100515" +%s)
timenow=$(date -u -d "$(date -u +"%Y%m%d %H:%M")" +%s)
if [ $(( ($timenow - $reftime) % 5100)) -eq 0 ]
then
php -q /home/myweb/public_html/check.php
fi

Code (markup):

Or does the script allow you to run it faster e.g. once per hour, would be simpler if it did.

 

Why cant you just run it as:

*/85 * * * * php -q /home/myweb/public_html/check.php

This should work fine afaik

 

If you try and enter */85 via cPanel it reports it as an error

 

You are right, it accepts only values 0-59 for minutes.. I think you will have to go for the solution you mentioned (via script)
