Linux - the DISPLAY environment variable

One interesting option regarding the DBCA (Database Configuration Assistant in Oracle ) , and I guess from many other programs, is to specify them through the DISPLAY environment variable where to send the windows they open .

This is standard X Window System—you set an environment variable DISPLAY to tell the program where to send the windows it opens. For example,export DISPLAY=10.10.10.65:0.0 will redirect all X windows to the machine identified by IP address 10.10.10.65, no matter which machine you are actually running the DBCA on.

This is great stuff! and it's kind of weird me just discovering it.
