Subject: Linux sys vars?

Hi,

I keep seeing a reference to what looks like two pre-populated variables in shell scripts.  Actually this one is in a crontab.

Something like this :  /home/user-name/directory-name/scriptname.php >/dev/null 2>&1

What is the number 1 and 2?  Is there others?

Thanks!
