Re: Copy files of the same name - keep newest one

By default, cpio does not restore existing files that are "newer or same age". The -u option has to be used to (u)nconditionnaly restore files. cpio cant take care of files >2GB.

If you know a file (you can maybe create one with touch) that marks the date
time of the transfer you can use find.  Suppose that file xxx has a time
stamp on it that any file before this time stamp is old and after this time
stamp is new.  Then

Find . -newer xxx

Will find all files newer in modified time then xxx.  There is another form
of -newer that allow you to specify which time value to look at (see man
pages).  Then feed these files in to the cp command.

I believe that will overwrite existing files.

If there aren't too many, you might use the "-i" flag, which will prompt you
before overwriting a file.
