Hi Anthony, changing permissions of files like you did with a recursive command is an accident that anyone can make. There are some general rules to reset directories as per the FHS or LSB and there are permissions set on files in .deb packages for files that are unpacked as well as 'statoverride' file to setup special files. But there is not an easy way to know what permission a files should have beyond having a backup of either the entire files itself or of just the permissions of the files. You can change the permission of any random file but apply a general rule to reset permissions will not take that into account. I had an accident where I deleted /bin by mistake. There is not a rule book on how to get the files back or on how to make them the correct version wrt your os or how to make the os reinstall the correct version. This is the same thing with file permissions. You simply repair the damage as best as you can and fix error as they come up, if you dont have a backup that would reasonably fix the problem, assuming you are not on a deadline. I guess the rule is think twice, type once :-) not that it always helps.
