And this is what you see in PowerShell 7.3.10. If the output does not end in a newline, `Out-File` and file redirection add a newline. **But in PowerShell 7.4.0, with file redirection that newline is no longer added.** \r\n\r\nTo make this easy to repro you'll want a native executable that outputs character data but no newline (LF or CR/LF) _at the end_. Here's a C# program that does that. You *don't have to* use this program to repro the problem. It just helps.\r\n```\r\nnamespace Example;\r\n\r\ninternal class Program\r\n{\r\n    static void Main()\r\n    {\r\n        Console.Write(\"Hello\"); // Note that it's not WriteLine()\r\n    }\r\n}\r\n```\r\n\r\nThis appears to be related to the PR: https://github.com/PowerShell/PowerShell/pull/17857 by @SeeminglyScience that was added in preview 4\r\n\r\nAppears to be related to #20747 and #20808.\n\n### Expected behavior\n\n```console\n# See \"Steps to reproduce\" for source code for Hello.exe\r\n\r\nPS\u003e .\\Hello.exe \u003ex.txt\r\n\r\nPS\u003e (Get-Content x.txt -Raw).EndsWith([System.Environment]::NewLine)\r\nTrue\n```\n\n\n### Actual behavior\n\n```console\n# See \"Steps to reproduce\" for source code for Hello.exe\r\n\r\nPS\u003e .\\Hello.exe \u003ex.txt\r\n\r\nPS\u003e (Get-Content x.txt -Raw).EndsWith([System.Environment]::NewLine)\r\nFalse\n```\n\n\n### Error details\n\n```console\nN/A\n```\n\n\n### Environment data\n\n```powershell\nName                           Value\r\n----                           -----\r\nPSVersion                      7.4.0\r\nPSEdition                      Core\r\nGitCommitId                    7.4.0\r\nOS                             Microsoft Windows 10.0.19044\r\nPlatform                       Win32NT\r\nPSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}\r\nPSRemotingProtocolVersion      2.3\r\nSerializationVersion           1.1.0.1\r\nWSManStackVersion              3.0\n```\n\n\n### Visuals\n\n### 7.3.10\r\n![image](https://github.com/PowerShell/PowerShell/assets/66026737/459ff3b6-8bdd-4a09-b938-881339997748)\r\n\r\n### 7.4.0\r\n![image](https://github.com/PowerShell/PowerShell/assets/66026737/adb8fc2a-e7a0-4e18-95cc-490823b78d7a)\r\n","author":{"url":"https://github.com/twinter-amosfivesix","@type":"Person","name":"twinter-amosfivesix"},"datePublished":"2023-11-29T17:55:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/20811/PowerShell/issues/20811"}
