in thread Odd file rename

To be honest, I don't see where rename() would be less robust than the link() / unlink() combo. Both cases work only on the same file system, both cases do otherwise the Right Thing, except that rename() is atomic, where link / unlink are two different statements. In the case of failure, both statements leave the original file untouched, but if the unlink() fails, you are left with an additional link to the old file, which is not always what you want ...

Update : And even Larry Wall claims that rename is cool :

Besides, REAL computers have a rename() system call. :-)

    I proposed the link/unlink solution because IMHO it allows for finer granularity of error handling (not that my example took advantage of this, but I could have). Also, according to this earlier perlmonks article rename a user was experiencing rename failures which ended up deleting the file being renamed.

    Of course, this shouldn't be an issue if the perl rename function really just calls the system rename call. I guess this depends on which OS you are running.
