rsync - Nov 2008 - DO NOT REPLY [Bug 5887] New: RFE: --link-any-dest option considers contents only, ignores name

https://bugzilla.samba.org/show_bug.cgi?id=5887

           Summary: RFE: --link-any-dest option considers contents only,
                    ignores name
           Product: rsync
           Version: 3.1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: Dave@Yost.com
         QAContact: rsync-qa@samba.org


Use case: say you have a directory full of media files on the source, and you
copy them all to the destination. Now you rename some or all of the source
files. You want rsync to rename the files on the destination to match the
source. So you might do this:

rsync -av --delete --link-any-dest=.  .

rsync would checksum all files in the source and destination hierarchies. If a
destination file is found with checksum matching the source, the link is made
if the contents are identical, whether or not the filenames are identical.
After this is all done, then --delete operations would take place.

------- Comment #1 from matt@mattmccutchen.net  2008-11-11 06:08 CST -------
The --detect-renamed option added by detect-renamed.diff does some of what you
want: it scans only extraneous files in the destination directory (not another
directory), and it compares only size and mtime, not contents, though the
potential matches it finds are just used as basis files for delta transfers
instead of being assumed to have identical contents.  Note also
link-by-hash.diff.
