What Are Cron Job Commands - What are they?

OK, OK, so I just figured out what a Cron Job is in Cpanel... There's a command, there's an email, and there's a time... Email to send you the results, time to set how repetitive it gets and command... what's the command for? I have no idea what to put for the command? Are there a list of commands or do you make your own? What language is it suppose to be in? Is it just an address, or do you have this 'crontab' thing infront of it or something... I just want to use it to update how many days of hosting I have left from this forum to my website... Is there a script somewhere that can do that? Please do help, I want to familiarize with all the functions in Cpanel. I found this: http://www.redhat.com/docs/manuals/linux/R.../cron-task.html and it describes what a Cron Job is. I know there's bash and crontab... WHAT DO THEY DO lol...?

Cron jobs and crontab are the linux version of your Windows Scheduler, i.e. they run certain tasks at specified intervals. Cron comes from the word "Chronology".

crontab is the Cron Table which stores records for all your cron jobs.

Now, the "commands" that you seek are actually unix shell commands/scripts - for that you need to refer to unix shell commands guide - there are plenty of bash scripting and command guides on the net along with online man pages. Just check them out - there are too many commands to describe in here...

We're designing a page so that users can check their credits without logging into the board. Once that is done, you can use that to fetch the values (using perl/php(curl) in crontab) to fetch the value and then plug it into your site maybe.

Curl (Client URL) or as it is commonly known - cURL - is an advanced set of libraries with prebuilts functions for easy URL parsing. Just check on the php site to know more about cURL. Particularly when you write data-mining code - to extract data from other sites and re-format and display it on your site - these libraries come to real handy...

Curl supports a wide variety of protocols - so you can fetch data from literally any source...
