Find directories and files with permissions other than 775 / 664 I am moving a website from one server to another and Git does not store metadata such as file permissions. I need to find the directories and files that are not 775 / 664 respectively. Right now, I'm using this cobbled-together contraption: $ find . -type d -exec ls -la {} \; | grep ^d | grep -v ^drwxrwxr-x $ find . -type f -exec ls -la {} \; | grep -v ^d | grep -v ^-rw-rw-r-- | grep -v '.git' Though this works, I feel it is rather hacky. Is there a better way to do this, perhaps a canonical way, or should I just be hacky? This is running on a recent Ubuntu version with GNU tools under Bash.

Use the `-perm` test to `find` in combination with `-not`:


find -type d -not -perm 775 -o -type f -not -perm 664


* `-perm 775` matches all files with permissions exactly equal to `775`. `-perm 664` does the same for `664`.
* `-not` (boolean NOT) negates the test that follows, so it matches exactly the opposite of what it would have: in this case, all those files that don't have the correct permissions.
* `-o` (boolean OR) combines two sets of tests together, matching when either of them do: it has the lowest precedence, so it divides our tests into two distinct groups. You can also use parentheses to be more explicit. Here we match directories with permissions that are not `775` and ordinary files with permissions that are not `664`.



If you wanted two separate commands for directories and files, just cut it in half at `-o` and use each half separately:


find -type f -not -perm 664
find -type d -not -perm 775
