Command line GUID for Unix and Windows?

Question

Is there a command line tool for Unix and Windows that uses the same algorithm to create GUIDs for both platforms?

Answer 1

There are tons of online apps to do it.

If you are using PHP, you can use the uniqid function.

I found a pure Java program to do it at http://jug.safehaus.org/. That should work anywhere you can install Java.
