echo ${!My*}
How does this simplify reporting  Redhat 567 ?

If
MyDog=Redhat
and
Mywife=567
then you might run
for v in ${!My*} ; do echo ${!v} ;  done
But it seem easier to use an array
My=(Redhat 567)
echo ${My[*]}

I think that you want to see the values along with the variable names.

If so, try

set | grep '^My'

But if you want to see just the values, try

set | grep '^My' |cut -f2 -d"="

I have a script that figures out a lot of stuff on a system and has 30 varables now and going for hundreds

If I use logical names like  network.interface.eth0
                                            network.gateway
                                            filesystem.root
                                            filesystem.user
I could use grouping names for my reporting.  If I am checking systems that are running for a while I would care about file systems. If I just rebooted, I would care about interfaces ( usually bonds )
