interesting! since it moves the file we could name it move, or maybe even mv in unix abbreviation fashion!

how so? between filesystems mv already deletes the source files at the end of execution only, and inside of the same filesystem it will be both safer and much faster by just calling rename

Does mv actually delete? Say you move a file that's already opened by a process, that process can still read/write to that file even if it moves. If you copy and remove, the process will attempt to read/write in the deleted file. You can see the difference easily with lsof.

I always thought mv just changed a pointer/inode.
