Because it is located inside the .git directory, it is entirely local to your machine. It is pushed to remote repositories like GitHub or GitLab, and it should never be added to your .gitignore file. Common Issues and How to Fix Them
While convenient for tiny, inconsequential changes, relying entirely on -m bypasses COMMIT_EDITMSG altogether. This encourages poor documentation habits.
Understanding the lifecycle of this file is crucial. When you initiate a commit, Git either generates a default message (for merges, squashes, etc.) or creates a blank template. It then opens your editor to display the contents of this file for you to modify.
COMMIT_EDITMSG is a temporary file stored in your .git/ directory. When you initiate a commit, Git generates this file to hold your commit message while you edit it. Once you save the file and close your editor, Git reads the content, finishes the commit, and then clears the file for the next time. Why You’ll See It COMMIT-EDITMSG
Most developers never look inside this file. They see the editor window pop up, assume it’s just a blank text box, and type git commit -m "fix bug" . They are missing the point entirely.
: You are 30 lines deep into explaining a complex bug fix in your editor. You hit save, close the tab, but the terminal shows: Aborting commit due to pre-commit hook failure . Recovery : You panic, thinking your message is lost. It is not. Open .git/COMMIT_EDITMSG in any text editor. Your full message is waiting for you. Fix the hook issue, and run git commit again; Git will open that same saved message for you.
To complete this "story" and finish your commit, follow these steps: 1. Write the Narrative Because it is located inside the
The -m flag is convenient for short messages, but it completely bypasses the COMMIT-EDITMSG workflow. This means you also bypass the powerful features that come with it: templates, hook validation, and multi-line editing.
Tools like git-super-ai , gpt-commit , or custom scripts work by:

Your terminal pauses, and a text editor springs to life, often displaying an empty file or one with a few cryptic lines. That blank canvas is your .git/COMMIT_EDITMSG file, but it's far more than just a text box. It's Git's dedicated workspace for one of the most critical documents in software development: . This encourages poor documentation habits
A high-quality commit message typically consists of three parts Subject Line : A brief summary (max 50 characters). Blank Line : Critical for separating the subject from the body : A detailed explanation wrapped at 72 characters per line Core Rules for Better Content
Because COMMIT_EDITMSG is a physical file, it provides a perfect integration point for automation. Git provides specific scripts called "hooks" that run during the commit lifecycle. The commit-msg Hook
The .git/COMMIT_EDITMSG file is the final handshake between your local development environment and the eternal history of your project. It is the silent document that stands between chaos and clarity in version control.
"You can use this hook to detect the presence of the words white space and then exit and provide a warning to the user that they need to have a better commit message."
Because COMMIT_EDITMSG relies on an external text editor handing control back to Git, it is a frequent source of confusion for developers. Here are the most common issues and how to resolve them. 1. Terminal is Stuck or Frozen
