To lowercase the names:
$ for file in *HTM; do mv $file `echo $file | tr A-Z a-z`; done
then you can change the extension from .htm to .html
The trick aboave was embedding a shell command within `backtics`.
It get executed before the command is evaluated. e.g.
$ echo TESTING | tr A-Z a-z
testing
(See also the `mmv' command in the mmv package for another way to
do these things).
