Re: 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.	[reply]
