tar and hidden files

Show all headers | View raw

I am using a command

tar czf out.gz --newer-than TS input-directory
touch TS

Every time I run this it creates out.gz containing a list of files of 
the form

path/._file-name

It does this for every file in the directory tree.  If there actually 
are newer files, I also get those.

The problem is, when I run the following in an empty directory

tar xf out.gz

it creates zero length files for all the entries in out.gz.  However, if 
files of this name already exist, nothing seems to happen.

Is that actually the case or are the existing files being altered in 
some way.  If that is happening, how do I prevent it?

From an intellectual standpoint, what are these files?  They take up 
space but don't seem to exist.
