Operating Systems OS X (Apple) What's the reason behind having -n option for mv command? Post 302967798 by scrutinizerix on Sunday 28th of February 2016 11:55:58 AM

What's the reason behind having -n option for mv command?

Sorry for a question that may seem dumb but learning UNIX basics I still can not grasp benefits of using
Code:
mv -n source file target file

I can understand the need for
Code:
 cp -n source file target file

when you get a copy with contents untouched but the former baffles me.
I know that this about preventing from overwriting a target file with contents of a source file (not in opposite order, right?) but why rename at all if you don't want to annihilate the target file? What's the point?

Would be glad to feel enlightened on the subject.
