cron job on webserver

the last days I have researched about cron jobs. First I want to tell you abaout my problem. I want to run a php script on my webserver every minute without loading the page. this php script inserts some data via yql. I read that cron is just working with unix/linux. my server runs on unix (wait for it). is it now possible for me to let my script run while sleeping in bed (computer off) just by the server side? do I got this all right? if yes, I also have to know how the path have to be look like in my command part in my schedule, because every example contents something like "* */1 * * * /usr/bin/wget http://www.example.com/cron.php", but why there is /usr/bin/wget in the path (that means, this cron is running just from my computer system not from the webserver) and how to put my schedule on the server and better where. my server have the root public_html where my index.php is inside. please give me an example of the schedule and how to fire my php data called "to_fire.php" that puts the data on my database via mysql.

I hope that some of you know what I exactly mean by own experience. im kinda confused by this command part and how to let it run from just the webserver and not my computer system.

thanks

  1. wget is a unix command to visit a web URL. curl is another command working similarly. You could also use php path\to\script.php to run, as Gigawatt mentioned. There is no big difference from all of them

  2. * */1 * * * is to set cron timing.

  3. /usr/bin/wget is the location where wget on your server

  4. Yes, once cron set, you can leave it alone. As long as server is living, the cron will run as scheduled. You can even set cron to send you an email, but that's no applicable to your case as running per min is to short.

  5. Running cron per min seems not common. If you are doing something like realtime update, consider other solution.

  6. Cron can be set on cPanel.

  7. You need to config your cron script to accept request from same server only, to avoid others access this URL.
