Hi Andrew,
That is a very elegant one liner. So this one just changed the H to a J
Let's see if some light is entering the brain at this late hour
So this - for x in 6H9* - is saying for the input 6H9* (all files in the
directory with 6H9as a prefix) then do the exchange of the J for the H
using the move command mv which is another way to rename; -v for
verbose will print the outcome on screen and after that it looks like
the swap but I am lost from this point. But grateful.
Thanks Andrew Greig
