Here is a literal example attached — the README from turbo assembler The very last character is ^Z (or ASCII 26 or 0x1A)
As it is, file says data for it Remove that char and file recognizes it alright # With ^Z at EOF $ file README README: data $ With ^Z removed $ file README README: ASCII text, with CRLF line terminators $ PS At first I thought to file the bug upstream but that takes me to a 1987(!!) webpage: https://www.darwinsys.com/file/ ** Attachment added: "README" https://bugs.launchpad.net/ubuntu/+source/file/+bug/2122399/+attachment/5908034/+files/README -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to file in Ubuntu. https://bugs.launchpad.net/bugs/2122399 Title: file doesnt recognize MSDOS text files Status in file package in Ubuntu: Incomplete Bug description: It was traditional in MS-DOS to end text files in a control-Z (ASCII codepoint 26 or 1A-hex) However this last character throws off file and it says "data" Removing it says ASCII text with CRLF line terminators ProblemType: Bug DistroRelease: Ubuntu 25.04 Package: file 1:5.45-3build1 ProcVersionSignature: Ubuntu 6.14.0-29.29-generic 6.14.8 Uname: Linux 6.14.0-29-generic x86_64 ApportVersion: 2.32.0-0ubuntu5.3 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Tue Sep 9 13:41:18 2025 InstallationDate: Installed on 2021-12-22 (1356 days ago) InstallationMedia: Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012) SourcePackage: file UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/file/+bug/2122399/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
