in reply to unix commands and perl modules war

I haven't noticed a module to do the work of *mv* across file system mount points. If anybody knows of one (besides issuing a call to *mv*), please let me know.

    Worse still, there's no flag you can give mv to stop it moving across file systems!
    "This is the Unix philosophy:
    
        Write programs that do one thing and do it well.
        Write programs to work together.
        Write programs to handle text streams, because that is a universal interface." 
    
    (my bolding)

    So mv is a wrapper around the rename() system call but it also includes cp -r and rm -r whether you want them or not. It wouldn't be so bad if it was a reversible operation but if any of your files were hard links then you're screwed.
