How to unpack a git repository *.pack files using PowerShell?

Question

I am aware of this question How to unpack all objects of a git repository?, but it doesn't help with PowerShell, I googled and even used ChatGPT, but no success yet.

Any help? How to unpack a git repository *.pack files using PowerShell?

Answer 1

I adapted this comment:

You need to move the pack objects outside the .git/objects/pack directory before using the command. However, the pack files need to be inside the repository.

For example, create a directory name SAMPLE in your project's root. Then, move the pack files to SAMPLE directory.

After that, inside the repository without the pack files, call this PowerShell Core command:

Get-ChildItem -Path SAMPLE/*.pack | ForEach-Object { Get-Content -LiteralPath $_ -Raw -AsByteStream | git unpack-objects }

If you're using the older Windows PowerShell (5.1), use -Encoding Byte instead of -AsByteStream.

You should see output as follows:
