Crontab - How to verify a PHP script Runs Successfully or not in a Cronjob Shell Script?

  • 772

I have below crontab in the system (Centos 7.9), However i am unable to verify if this runs correctly or not,

i.e if the crontab finds the PHP enr. variables or if the crontab has executed correctly without any errors in the shell or if the crontab entry has syntax issue ..etc

Any suggestion on how to do debug or capturing the output of a crontab like this one below

0 */1 * * * /var/www/example.com/scripts/cron.sh >> /var/log/app/cron/cron.log

Script content is like below

[root@]# cat /var/www/example.com/scripts/cron.sh
#!/usr/bin/env bash

cd /var/www/example.com/public
php cron.php

Is there better way to do this?

centos php cron

  1. You can run the following

    $ echo $?

    If you get 0 meaning is OK, a other value over 0 is not ok.

    ($?) Expands to the exit status of the most recently executed foreground pipeline.
