Public bug reported:
I mv'd a file to a directory where I had group write permissions, but a
file existed owned by another user. I was asked if I wanted to override
the permissions. I said "y". The ownership was changed on the
destination file to me, but the mod time and contents of the file were
not changed and the source file was deleted. I tried to duplicate the
behavior, but it worked as it should with a test file.
toma@admn1:~$ ls -ld /opt/scripts
drwxrwxr-- 3 ansible ansible 4096 Jun 24 16:25 /opt/scripts
toma@admn1:~$ mv GeneratePortList.pl /opt/scripts/
mv: replace '/opt/scripts/GeneratePortList.pl', overriding mode 0755
(rwxr-xr-x)? y
toma@admn1:~$ ls -l /opt/scripts/GeneratePortList.pl
-rwxr-xr-x 1 toma domain users 2855 Jul 16 2018
/opt/scripts/GeneratePortList.pl
I have mv aliased to mv -i so I can confirm that the existing
destination file was not owned by me since I was not prompted to
overwrite the file.
Both source and destination are in the same file system. I cannot find
the source file anywhere.
