   I'd recommend keeping the "ls".  Try your script when MAGDIR doesn't
   have any zipfiles, and MAGFILE will hold the expanded value of $MAGDIR
   with the string "*.[Zz][Ii][Pp]" appended.  Bash, sh, and ksh all do
   that for some dopey reason, which is why I would do

      for file in $(ls $MAGDIR/*.[Zz][Ii][Pp] 2> /dev/null); do  ...

   if there's any chance that you won't find any files.
