I wrote a PHP script that push a CSV file into a database. I want to do this automatically every minute. I know there is a way via cron on Linux but I don't know anything about bash and think cron can't give my PHP file a callback, so I can show a progress bar for the user to see the timer interval. What do I do?
You can enter your jobs using crontab -e. If your default editor is vi, I recommend to change it nano using export EDITOR=nano because it is easy to use for starters.
Every line of the crontab file represents a job. The first 5 tokens are : minute, hour, day of month, month, day of week respectively, the last one is command so in your case first 5 tokens will be * * * * * that means run this job every minutes when the second is '00'.
You can call your php files directly using this command : php /var/www/cron.php & or using a browser wget -O /dev/null http://example.com/cron.php If you use first one you cannot use some $_SERVER variables but if you use second one, it is like a real browser.
In your case you can use like this :
* * * * * wget -O /dev/null http://example.com/cron.php
