bug#18214: How to copy modification date with cp?

[Holger Klene]

Hello!

 

I'd like to copy photos from my harddrive to an external USB-drive for my parents. As there are many more photos on my harddrive, that I don't want to copy to my parents, I created a view folder with symbolic links that point exactly to the folders my parents should get.

 

Now I copy the contents of the view-folder over to the USB-drive with:

cp -vLRu viewForMyParents usb

 

After some time, more folders are added and I plan on repeating the copy command to update the usb-drive with the latest additions.

 

The problem is, all files and folders get a timestamp of the moment, when the copy took place instead of the original files timestamp.

 

I reproduced the setup and took a screenshot (cp-error.png). Only that the tar did not preserve the symbolic links inside test/myHardDrive/viewForMyParents/

 

My question is, how can I make cp not updating the timestamps to the moment of the copy (e.g. 11:00) but instead let it copy the original files last modified (e.g. 10:something)?

 

Thanks

Holger

 

PS: This is Kubuntu 14.04 with cp (GNU coreutils) 8.21
