I have recently found a very odd issue I have not encountered before.

╭─daemonslayer2048@desktop ~ 
╰─$ ls -l /tmp/project                            
ls: cannot access '/tmp/SpeedTest/lib': Permission denied
ls: cannot access '/tmp/SpeedTest/First_Boot.py': Permission denied
ls: cannot access '/tmp/SpeedTest/help.sh': Permission denied
ls: cannot access '/tmp/SpeedTest/ResetDefaults.py': Permission denied
ls: cannot access '/tmp/SpeedTest/Manager.py': Permission denied
ls: cannot access '/tmp/SpeedTest/Maintenance.py': Permission denied

-????????? ? ? ? ?            ? help.sh
d????????? ? ? ? ?            ? lib

-????????? ? ? ? ?            ? Manager.py
-????????? ? ? ? ?            ? ResetDefaults.py

Is anyone familiar with what may be going on here? Did something get corrupted? I tried searching first but I only seem to get explanations of file permissions nothing to explain how this happened and if I can fix it. I tried setting an owner and permissions to the files but they remain unchanged.

Edit: Added ls -ld of project folder.

╭─daemonslayer204@desktop ~ 
╰─$ ls -ld /tmp/project/

    Please add the directory permissions of `/tmp/project` to the question (`ls -ld /tmp/project`). Looks like the executable bits are not set. – Freddy Jun 18 '20 at 18:55
  • Added the edit you requested. Why did that fix this? Why does the folder need to be executable to be able to ls files in a directory without getting the "?". I am seriosuly lacking some information/understanding apparently. – DaemonSlayer2048 Jun 18 '20 at 19:51

    @DaemonSlayer2048 I'm not finding a good reference right now, but the point is that, while having read permissions on a directory lets you read its (d)entries (i.e. list the names of the files inside it), it doesn't allow you to traverse it. Traversing requires "search" permissions (that's `x` (execute) for directories) and is necessary in order to access the inodes of the contained files, which store their metadata (including ownership and permissions). – fra-san Jun 18 '20 at 20:08
