如何从Git存储库中提取对文件夹/归档的所有提交的所有文件？

Question

I have a Git Repository. I want to export all files and folders from my repository history, based on the different commits, into a folder. But I want to export all commits and branches separately. A sort of backup/archive for my git repository.

For example if I have a repository history of:

-v2.0 My Latest commit -v1.0 My Initial commit

I want to export all files and folders of these different commits into separate folders. I want the files as normal complete files not as a difference patch.

For example the folders "/MyGitBackup/Master/v1.0" and "/MyGitBackup/Master/v2.0" which should include the files of the according commits.

How can I achieve this? Is a GUI tool capable of this or something similar? I use a Windows machine.

Answer 1

You can use git worktree <path> <commit> that enables to checkout different commits to different directories. So, execute the following commands in your working directory:

git worktree add /MyGitBackup/Master/v1.0 <v1.0 commit hash or tag>
git worktree add /MyGitBackup/Master/v2.0 <v2.0 commit hash or tag>

That sounds like a waste of space. But sure it's possible:

• For each revision, as per the git rev-list command
• Run git archive revision with the appropriate flags

This is one way to export the content of each revision in master to a separate folder in a sub-directory of archive/ :

git rev-list master | while read rev; do
    echo creating archive for $rev
    mkdir -p archive/$rev
    git archive $rev | (cd archive/$rev; tar x)
done
