Description: Ubuntu 24.04.2 LTS Release: 24.04 The package is not really known, but NTFS3 seems to belong to the Linux kernel. $ cat /proc/version_signature Ubuntu 6.8.0-63.66-generic 6.8.12 What is expected: 1. command stat should show information about the hidden state. 2. command find should find such "hidden" files. 3. command ls should have a switch to list such "hidden" files. Discussion base is the following user directory on a Windows NTFS partition: C:\Users>Attrib Praxis\* /D R C:\Users\Praxis\3D Objects C:\Users\Praxis\Anwendungsdaten H C:\Users\Praxis\AppData R C:\Users\Praxis\Contacts SH I C:\Users\Praxis\Cookies R C:\Users\Praxis\Desktop R C:\Users\Praxis\Documents R C:\Users\Praxis\Downloads I C:\Users\Praxis\Druckumgebung R C:\Users\Praxis\Eigene Dateien R C:\Users\Praxis\Favorites R C:\Users\Praxis\Links C:\Users\Praxis\Lokale Einstellungen R C:\Users\Praxis\Music I C:\Users\Praxis\Netzwerkumgebung A H I C:\Users\Praxis\NTUSER.DAT A SH C:\Users\Praxis\ntuser.dat.LOG1 A SH C:\Users\Praxis\ntuser.dat.LOG2 A SH C:\Users\Praxis\NTUSER.DAT{53b39e88-18c4-11ea-a811-000d3aa4692b}.TM.blf A SH C:\Users\Praxis\NTUSER.DAT{53b39e88-18c4-11ea-a811-000d3aa4692b}.TMContainer00000000000000000001.regtrans-ms A SH C:\Users\Praxis\NTUSER.DAT{53b39e88-18c4-11ea-a811-000d3aa4692b}.TMContainer00000000000000000002.regtrans-ms SH C:\Users\Praxis\ntuser.ini R C:\Users\Praxis\OneDrive R C:\Users\Praxis\Pictures R C:\Users\Praxis\Recent C:\Users\Praxis\Roaming R C:\Users\Praxis\Saved Games R C:\Users\Praxis\Searches R I C:\Users\Praxis\SendTo R C:\Users\Praxis\Startmenü R C:\Users\Praxis\Videos I C:\Users\Praxis\Vorlagen The folder C:\Users\Praxis\AppData is flagged with the HIDDEN attribute.

In other words, there is no way to test, if a file is marked hidden or not and no such property is known in POSIX terminology, but in fact it is not listed by ls -al. Surprisingly with the -d switch ls reports about this file: $ ls -ald /mnt/Daten/Users/Praxis/AppData drwxrwxr-x 1 praxis praxis 0 Jul 9 00:39 /mnt/Daten/Users/Praxis/AppData On the other hand, it is not findable: $ find /mnt/Daten/Users/Praxis/ -name AppData $ This is very confusing, that there is no terminology which describes this special difference to normal files, and the handling looks inconsistent. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: praxis 1469 F.... pulseaudio /dev/snd/controlC0: praxis 1469 F.... pulseaudio CRDA: N/A CasperMD5CheckResult: unknown CurrentDesktop: Unity:Unity7:ubuntu DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2025-07-08 (13 days ago) InstallationMedia: Ubuntu-Unity 24.04.2 LTS "Noble Numbat" - Release amd64 (20250215) MachineType: LENOVO 20BE00B1GE Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.14.0-24-generic root=UUID=472cb8a3-1524-4ae9-858a-043812227ced ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 6.14.0-24.24~24.04.3-generic 6.14.6 RelatedPackageVersions: linux-restricted-modules-6.14.0-24-generic N/A linux-backports-modules-6.14.0-24-generic N/A linux-firmware 20240318.git3b128b60-0ubuntu2.14 Tags: noble Uname: Linux 6.14.0-24-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 06/03/2021 dmi.bios.release: 2.39 dmi.bios.vendor: LENOVO dmi.bios.version: GMET91WW (2.39 ) dmi.board.asset.tag: Not Available dmi.board.name: 20BE00B1GE dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.ec.firmware.release: 1.15 dmi.modalias: dmi:bvnLENOVO:bvrGMET91WW(2.39):bd06/03/2021:br2.39:efr1.15:svnLENOVO:pn20BE00B1GE:pvrThinkPadT540p:rvnLENOVO:rn20BE00B1GE:rvrSDK0E50510WIN:cvnLENOVO:ct10:cvrNotAvailable:skuLENOVO_MT_20BE: dmi.product.family: ThinkPad T540p dmi.product.name: 20BE00B1GE dmi.product.sku: LENOVO_MT_20BE dmi.product.version: ThinkPad T540p dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2117110/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
