I have finished doing the work but did it manually.  For future reference,
I'd like to re-learn what I forgot from 20+ years ago about how to do this
the easy way.  Basically, I had a directory full of files that I wanted to
process all the same way and rename them in the process.  What I could not
remember was how with globbing, I could specify the output name part that
was wild-carded in the input should be used in the output.

Lets say I have a bunch of files named Screenshot-PXEmenu-*.png and I want
to copy or rename them to PXEmenu-*.png.  Both mv and copy fail
(understandably?) using "<command> Screenshot-PXEmenu-*.png PXEmenu-*.png".
I am pretty sure there is a way to make one or both work with a syntax for
the target I do not remember.  Any clues?

The names are real, though what I was really doing was using the convert
command of ImageMagick to negate all the colors in those screenshots so I
had a specified input and output file anyway.  NTL, the base question here
is the real one.
