Subject: deleting directories matching a pattern

I cannot believe I'm having trouble with this - it should be utterly
trivial, but I just can't get Ruby to work correctly on this.

I've got a directory with subdirectories that have names such as
"Eb97503.120822", where 97503 is a job submission number, and 120822 is
a time-date stamp.  So the directory contents might look like this:

Eb97503.120622
Eb97504.120622
Eb98537.120722
Eb99659.120822

I want to pattern match the job submission number, and delete the
directories.  I must have tried ten different ways of doing it using
strings set with the job submission number, but I just can't get it to
work.

How the heck do I delete the middle two directories, once I have strings
set as:

job1 = 97504
job2 = 98537

This is embarrassing....
