Shell command task on clearos fails to select correct PHP version

Fabio Montefuscolo requested to merge rdcongo/tiki:shell-command-task-on-clearos into 21.x

It seems without invoking the method Process::inheritEnvironmentVariables, some needed environment variables are not set on the child process. On ClearOS, it will make tasks to use the php5.6, even if you call the scheduler using php7.2 directly.

We have a tiki using cronjobs to trigger the scheduler, like below:

# Run Scheduler
* * * * * su apache -s /bin/bash -c 'cd /var/www/virtual/zzz.zzzz.zzz/html && /opt/rh/rh-php72/root/usr/bin/php -d memory_limit=256M console.php scheduler:run'

The error is something like below

After accepting this change, the cronjob should be something like
