Cmd mv: Owner/group copy

[Filip Kocina]

Hi all,

I'd like to ask you why the owner and the group of a file is retained
while moving a file via mv. I was surprised when I made a file as root
in home directory of another user and moved this file as this another
user into /tmp. I mean the preservation is rather logical, but if this
another user renamed this file to a not very smooth-tongued name, the
user who owns this file could be compromised. I know there is an easy
solution: not to move file into a directory of another user, but still,
this behavior of mv is little weird for me.

Thank you in advance for explanation.
