macOS List files with unusual permissions

[nelly22]

I would like to know what files/folders have wrong permissions and then repair permissions using Apple method and KCPM Utility and then reset some files permissions back to original what it was before repairing.

I’m pretty sure there is some unix tools or AppleScripts which goes thru all files/folders and lists permissions or just lists files which has wrong permissions.

Apple method sets all to permissions in Macintosh HD/Users/Me/ to Me read & write, staff read only, everyone read only.

Couldn't you just use Disk Utility?

How? I don't think Disk Utility repairs permissions anymore.

Woah! Shows how long it's been since I've looked at Disk Utility. You're right. It's not there anymore - since El Capitan, apparently:

Apparently it's no longer required since macOS deals with that sort of thing periodically, of its own accord.

Periodically? When?

From the above article:

Manual disk permission repair simply isn't necessary anymore. El Capitan automatically repairs file permissions during software updates and changes. So don't worry that the repair permissions option isn't available in Disk Utility anymore. It's become redundant, thanks to improved file integrity in El Cap.

...I assume this is correct, but I've not verified it myself.

The find command will enable you to look for specific permissions and you can also use the exec option to change those permissions. Warning unchecked code example:

find . -perm 707 -exec chmod 777 {} \;

True.

Although you need to be sure your find command is finding the right files, and know what permissions they should have. If you get it wrong then Bad Things© may occur.
