--compare-dest -- copy ONLY files with content-differences between 2 directories... to a third
Hi,
I'm having trouble with --compare-dest, to copy only files that differ in
content.
Here are the commands used thusfar:
rsync -av --checksum --delete --progress --stats --compare-dest=../old
new/ new_archive
rsync -av --checksum --delete --progress --stats --compare-dest=../new
old/ old_archive
old/
a.txt
new/
a.txt
Note: both a.txt are the same (except for a different timestamp).
a.txt contains just 2 characters: 'a' and '\n'
Now the problem: In the output I see a.txt get copied!!!
old_archive/
a.txt
new_archive/
a.txt
I do NOT want this!
Why is a.txt getting copied, when it is identical in its content?
Please can you help, so that only files that DIFFER IN CONTENT ONLY... get
copied.
Thanks.
John

--compare-dest -- copy ONLY files with content-differences between 2 directories... to a third
Hello, thanks for the reply, but I must confess: I don't understand it. How would I go about using rsync to copy only files with content difference between folder new and old (or existance-only in folder new)... from folder new to a third folder new_archive... ??? along the lines of: rsync -av --checksum --delete --progress --stats --compare-dest=../old new/ new_archive (I've been trying around with --ignore-times and --size-only... but that didn't lead anywhere...) Can this actually be done with rsync?
