Generally speaking, I find myself panicking when I realise that if I cancel a file move, it could cause the target or source to be incomplete. This question applies to Windows and Unix-based platforms. I can never remember exactly how the move command works in either case. For example, if you're moving a directory; does it copy the entire directory, and then delete it after, or does it copy and then delete each file individually?
I always realise, after typing something like
mv verybigdir dest, that I perhaps should have typed
cp -R verybigdir dest && rm -R verybigdir (where the
&& operator proceeds to the next command only if the first was successful) -- or is this pointless? What happens, exactly, when I press Ctrl+C half way through a move? Likewise, what exactly happens on Windows when I press the cancel button?
I can't count the number of times I've moved something (the last time was when using
svn) and had two directories, with split contents. I guess the answer is difficult, because not all applications move groups of files in the same way.
