           -s  Do not clear any mode bits if owner can't be set

           -v  Tell what mv is doing

     Mv moves one or more files from one place in  the  file  system  to
another.   If  the  old  path and new path are on the same device, it is
done by renaming otherwise by copying. If you're not superuser, the copy
will  destroy  the  file's owner, group and setuid/setgid bits.  mv will
prompt before removing non-writable files if stdin is a terminal or  the
-i flag was specified.
