Prevent job from double execution

Good night, community !

Having a problem. I have created custom job as described here https://aimeos.org/docs/2020.x/cronjobs ... ontroller/

I tell me, please, do you know good solution, how to prevent my job from being executed several times simulationasly ?

For example I will add my job to cron which run each 1 minute. But what if started job has not finished yet ? I don't want this task to be executed, to say exactly - it may be executed, but need to detect that this task is running and prevent to perform the job...

Just realized, maybe it is not aimeos related question. So if I set cron like:

Code: Select all

`* * * * * php /var/www/schmuck/artisan aimeos:jobs "order/email/delivery order/email/payment order/email/voucher order/service/delivery"`

how it works? Will it execute in 1 minutes if one of jobs is not finished ? - I just checked this, crontask keeps opening jobs...
Is it considered on standard aimeos jobs like

Code: Select all

order/email/delivery order/email/payment order/email/voucher order/service/delivery

??

You can create a shell script like this one:

Code: Select all

#!/bin/bash
if [ ! -f aimeos.lock ]; then
	touch aimeos.lock
	php /var/www/schmuck/artisan aimeos:jobs "order/email/delivery order/email/payment order/email/voucher order/service/delivery"
	rm aimeos.lock
fi

It tests if the "aimeos.lock" file exists and executes the jobs otherwise
