Hi,
I need to move the set of files, and it should be same time stamp as previous.
How to do this?
cp -p
will preserve as many of the permissions and time information as your access will allow in the new directory.
Whoops - you wanted mv. POSIX mv doesn't have an option for that, that I'm aware of.
there is no -p flag with mv, but you can use cp -p file dest/and remove the original file.
if the destination dir is on the same partition i think you can also use ln
