How can I unpack all objects of a pack file?
I've just cloned a remote repository, so my local repository currently doesn't contain any loose object, only a .pack and a .idx files.
I've tried running git unpack-objects < .git/objects/pack/pack-.pack, but nothing happens.
I'm doing something wrong? Is there any other command to do that?
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, use the command git unpack-objects < SAMPLE/*.pack. Git will generate all objects inside .git/objects directory of your repository.
