If the program runs off the end without hitting an exit() or die() operator, an implicit exit(0) is provided to indicate successful completion. If that can't be done, system administrators are strongly encouraged to put symlinks to perl and its accompanying utilities into a directory typically found along a user's PATH, or in some other obvious and convenient place. the default behaviour is not to randomise unless the PERL_HASH_SEED is set. For a discussion of issues surrounding file permissions and -i, see "Why does Perl let me delete read-only files? So this is just a fancy way to copy files: If, for a given file, Perl is unable to create the backup file as specified in the extension then it will skip that file and continue on with the next one compiler vendor/version dependent. line, or worse, doesn't even recognize the #!
