Clone ownership and group of coincident name files and folders between two servers

Question

I need to sync only ownership and group of each file and dir between two server filesystems. That's to say if I have server A and server B, I don't need and don't want to copy data from one server to other, I need to set the same owner and group from each file in B that exists in A. If a file/dir doesn't exist in A, or viceversa, I don't need to do nothing about, only to change owner and group of every file and directory that exists in both servers to the one of the file/dir in server A. I know that "chown --reference" make that, but I don't know how to use it for change according to other files and directories.

I wish I explained my question correctly.

Please, any suggestion?

Thanks in advance

Answer 1

Assuming that you don't mind trying to set ownerships on files that already have them correctly, I guess you could run something along the lines of

/bin/stat --format 'chown %u:%g %n' ~/.bash*

on server A, which will give you a list of chown commands to execute on server B. (You could pipe the whole thing through | ssh user@serverB.)

You'll get the occasional error for files that don't exist on B, but that would be harmless.
