As others noted, the ls command is superfluous and possibly harmful
One more thing you can do is case-insensitive pathname expansion:
shopt -s nocaseglob
for MAGFILE in $MAGDIR/*.zip
#lots of other stuff
That will work with bash (begin your script with #!/bin/bash) but not
with dash as far as I know.

Note that that is not a regular expression, it's a shell pattern or
glob pattern. They are different, and used in different contexts. Both
are immensely useful.
