A user reported that a folder he created on a share folder could not be seen by other users. I tried it on several different computers connected to the same shared folder. I could not see the folder that the user created using Finder. I then tried Terminal and issued this command
admin$ ls -l total 0 -rw-r--r-- 1 admin staff 0 Dec 13 17:16 test-file.txt [email protected] 2 admin staff 68 Dec 13 17:21 test-folder
The test-folder is the one that’s invisible under Finder. Notice the extra @ for the test-folder. This means that there are extra attribute keys and sizes for it. Using the command ls [email protected] reveals the extra info.
admin$ ls [email protected] total 0 -rw-r--r-- 1 admin staff 0 Dec 13 17:16 test-file.txt [email protected] 2 admin staff 68 Dec 13 17:21 test-folder com.apple.FinderInfo 32
For some reason, the folder was created with com.apple.FinderInfo 32 . This tells Finder that this folder is hidden- that’s why other people could not see it. To un-hide this folder, use this command:
chflags nohidden test-folder
Similarly, if you want to hide a file or a folder, use this command:
chflags hidden file-name
