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.
