Bug ID: 206192
Summary: ls -R warns about EACCES on directories it's not going
to list anyway
Product: Base System
Version: 10.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: f...@fuz.su
The FreeBSD implementation of ls -R decides to omit directories from recursive
listing which are omitted from listing anyway. This may be in violation of
POSIX [1] but that's irrelevant for this bug report. When ls -R encounters a
directory without reading permission, it outputs the resulting EACCES. This
even happens for directories which are never listed by ls -R anyway due to
their names beginning with a dot, which causes ls to output spurious warnings.
To reproduce, in an empty directory do:
mkdir .a
chmod a-r .a
ls -R .
The following output results:
$ ls -R .
ls: ./.a: Permission denied
If .a was readable, ls -R would not list it either, so the error message seems
wrong.
