Correct.  The script you showd processes a _single_ argument only.
Use a 'for loop' to handle multiple files, something like  --
   for thisfile in file.* do
    `mpost-eps $thisfile
   end

You were *close*.  what you wanted is (assuming MPOST and GS are defined:
  for file in {{list or wildcard}} do
   $MPOST $file
   $GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$ile.eps $file.1
  end
