 Hi Larry, if the files have spaces in them, I make my life easier and
run detox[1] on them first. Otherwise the command rename should do
what you want: rename FROMpattern TOpattern Files

rename Screenshot-PXE PXE Screenshot-PXE*

if the files had spaces you wanted to keep.. do a find with the
-print0 into an xargs with the -0 option that runs the rename.
also bash does slice up strings in variables - see # ## % %% - kind of
a match 'n scratch - good for scripting.
x=Screenshot
echo ${x#Screen}
