To configure Git to use Vim as your editor for commit messages instead of Nano, you can set the `core.editor` configuration. You can do this with the following Git command: ```bash git config --global core.editor "vim" ``` This command sets Vim as the default editor for all your Git repositories on your machine. If you only want to set Vim as the editor for a single repository, you can run the command without `--global`, making sure you're inside your Git repository's directory. Here are the steps to do that: 1. Open your terminal or command prompt. 2. Execute the following command to set Vim as the default editor globally: ```bash git config --global core.editor "vim" ``` 3. If Git asks you to commit or amend commits, it should now open Vim instead of Nano. Please note that for this to work, the `vim` command must be available in your terminal or command prompt. If `vim` is installed but the command is different (for example, `mvim` for MacVim on macOS), adjust the command accordingly. Additionally, if you're on a system where Vim is not the default command for Vim editor, or if it's not in the system's PATH, you might have to specify the full path to the Vim executable: ```bash git config --global core.editor "/path/to/vim" ``` Replace `"/path/to/vim"` with the actual path to the Vim binary on your system. To confirm that Vim is set as the default editor, you can check your Git configuration with: ```bash git config --global --get core.editor ``` This command should return `vim`, confirming the change has been made. Finally, anyone stumbling upon this question in future searches should note that while the command and configuration required to set Vim as the default editor in Git will likely remain the same, it is always a good idea to consult the latest Git documentation or `git help config` for the most up-to-date information on Git configurations.
