That fixes one problem, but there are plenty more still unfixed.

If the user input ("$1") is to be treated as an ERE, then you could
do something like this:

for filename in *; do
    [[ $filename =~ $1 ]] || continue
    ...
done

But your grep is treating "$1" as a BRE, not an ERE, and bash doesn't
have any implementation of BREs.

In any case, I do NOT recommend writing your own script to replace and
augment rename(1).  Just run a bunch of rename commands from the shell
prompt to make the filenames look how you want them.
