Use: find . ! -readable -prune or more generally find ! -readable -prune -o -print to avoid "Permission denied" AND do NOT suppress (other) error messages AND get exit status 0 ("all files are processed successfully") Works with: find (GNU findutils) 4.4.2. Background: The -readable test matches readable files. The ! operator returns true, when test is false. And ! -readable matches not readable directories (&files). The -prune action does not descend into directory. ! -readable -prune can be translated to: if directory is not readable, do not descend into it. The -readable test takes into account access control lists and other permissions artefacts which the -perm test ignores. For find versions without -readable test, you can check permissions: find . ! -perm -g+r,u+r,o+r -prune Adapted from stackoverflow: http://stackoverflow.com/questions/762348/how-can-i-exclude-all-permission-denied-messages-from-find
