Thanks for this, Jonas.  I appreciate your help.  I really must learn 
some bash sometime...

I tried the command.  I got a list of programs (as expected) but there 
are *1776* of them!!!!

I tried the same command with 64-bit substituted for 32-bit and got the 
exact same list (I used diff to compare them).

I'm confused...
