The git merge-repo command is another feature provided by the “git-extras” extension, which allows you to merge the histories of two Git repositories. It is useful when you want to combine the commit history and content of two separate repositories into a single repository.
To use the git merge-repo command, you need to have the “git-extras” extension installed. Once installed, you can execute the following command:
# git merge-repo [source-repo-url] [destination-repo-path]
In this command, [source-repo-url] represents the URL or path of the repository whose history you want to merge into another repository, and [destination-repo-path] is the path to the repository where you want to merge the histories.
The git merge-repo command performs the following steps:
- It clones the source repository into a temporary directory.
- It fetches all the branches from the source repository.
- It merges each branch from the source repository into the corresponding branch in the destination repository.
- It resolves any conflicts that occur during the merging process.
- It updates the commit history of the destination repository to include the merged changes from the source repository.
After executing git merge-repo, the destination repository will contain the combined history of both repositories, preserving the commit messages, timestamps, and changes from the source repository.
It’s important to note that git merge-repo is a powerful command that can alter the commit history of the destination repository. Therefore, it’s recommended to use it with caution and make sure to create backups of your repositories before performing the merge operation.
git-merge repo Command Examples
1. Merge a repository’s branch into the current repository’s directory:
# git merge-repo /path/to/repo branch_name /path/to/directory
2. Merge a remote repository’s branch into the current repository’s directory, not preserving history:
# git merge-repo /path/to/remote_repo branch_name .
