Greetings all.  I got some code from others here in two ways to find the number of AIX devices in the environment.

I have a question for you great folks.  See the below.  Can you tell me exactly what these mean?  The only difference is the |AIX.  Trying to understand the difference of the code here to define what might work, etc...

 

First (found 122 devices

^AIX((?!\/).)*$|AIX

 

Second (found 60 devices)

^AIX((?!\/).)*$
