Note that in all --*-dest options if the path is relative it is relative to the target dir not the "$PWD". I like to always use absolute paths because of this. But essentially, the command with the instances of $PWD vs without them the paths aren't the same. If you want all relative to . paths it would be: rsync -aHvv --compare-dest=../dstlt/. srclt/. baklt/.
Also, all these params that end with /. the . is kinda pointless despite being points ;) On 04/05/2017 07:19 PM, L A Walsh via rsync wrote: > just subscribed for rsync-qa from bugzilla via rsync wrote: >> Probably using different options?
