I'm working on setting up cronjobs using PHP script. I know how to set up single file as a crontab, for example - shell_exec('crontab testcron.txt');
Is it possible to set multiple files as a crontab, like -
shell_exec('crontab testcron1.txt testcron3.txt testcron2.txt'); shell_exec('crontab testcron1.txt,testcron2.txt,testcron3.txt');
Thanks.
