Under cygwin, .bak is the default.  From perl's README.cygwin:
   Inplace editing C<perl -i> of files doesn't work without doing a backup
   of the file being edited C<perl -i.bak> because of windowish restrictions,
   therefore Perl adds the suffix C<.bak> automatically if you use C<perl -i>
   without specifying a backup extension.

Other options are sed or awk.
