A script has an execution time of more than a minute. So, therefore I would like to run the script as a background task.
I've read a lot about it on the internet and read that
print shell_exec('/usr/bin/php -q page.php &'); isn't the solution since the taks is still a child of the process. I've tested it with sleep(10) and indeed, the page which should call the cron job is waiting for 10 seconds.
So, symcbean have written an article ( http://symcbean.blogspot.nl/2010/02/php-and-long-running-processes.html?m=1 ) and is suggesting the following code:
print `echo /usr/bin/php -q longThing.php | at now`;
But, unfortunately, i script didn't do anything and after adding
2>&1 I get the following response:
sh: at: command not found
I've search a lot for solving this issue, but can't find any solution.
