Kiraly,
Thanks. I know the chown command from my time spent administering a Linux-based webserver. Same goes for applying ownership recursively. However I know invoking root authority is not something to be taken lightly. Your commands appear to work on some files, however Terminals gives an "Operation not permitted" error on many others. The files to which I did successfully apply both commands I was able to move, though it did ask for my admin password beforehand.
I'm still a bit concerned that I've messed something up. If I ctrl-click < get info on files or folders I've created in my own user account, and look under the sharing and permissions section, most list ownership as:
- User (Me) – read & write
- staff – read only (or else it's not listed)
- everyone – read only (or else "no access")
Files to which I've applied the commands you listed somewhat different permissions:
- User (Me) – read & write
- _unknown – read only
- everyone – read only (or else "no access")
In some cases my username is listed twice, both as user owner and group owner. I'm worried that by leaving permissions like this, I'm going to create problems for myself in the future. Is there some easy to fix these permissions, or should I just delete everything and run Migration Assistant again? I had considered running the following command:
sudo chown -R username:staff /folder
However I am not user if that is correct, if admin users are part of usergroup "staff"; also, that command mentions nothing of usergroup "everyone".
