Commit-editmsg

Git performs the following steps:

The file lives at the root of your local Git administration folder.

Think of COMMIT_EDITMSG as Git’s . Just as the staging area ( git add ) allows you to curate which code changes go into a commit, COMMIT_EDITMSG provides a curated environment for the message that will explain those changes.

| Problem | Example | Fix | |---------|---------|-----| | | (no body) | Add why and how for non-obvious changes | | Just repeats subject | “Fix login bug – fixed the login bug” | Delete redundancy | | No reasoning | “Changed max length from 50 to 100” | “Increase max length to 100 because API now accepts up to 100 chars” | | Internal references missing | “Fixes issue” | “Fixes #427 – rate limiting on mobile” | | No “why” for breaking changes | “Changed config format” | “BREAKING CHANGE: config uses YAML instead of JSON – migration script in /docs” |

When your text editor launches during a commit, the file typically looks something like this:

You think your message is gone.

: Always leave a completely blank line (line 2) between your subject line and the detailed body description.

If you have ever peeked into your project's .git folder, you have likely seen a file named COMMIT_EDITMSG . Most developers ignore it, but understanding this file is the secret to fixing failed commits, creating consistent templates, and automating your workflow.

The file is a temporary text file generated automatically by Git inside the hidden .git directory whenever a developer runs the git commit command without the inline -m flag. It serves as Git's native staging ground for crafting, editing, and finalizing version control commit messages before they are permanently baked into your project history. Git performs the following steps: The file lives

You spent 10 minutes writing a detailed commit message in Vim. You save and quit, but Git aborts the commit because you forgot to stage a file (e.g., nothing to commit ).

Git hooks are scripts that run automatically before or after specific Git actions. The commit-msg hook operates directly on the COMMIT-EDITMSG file. Teams use this hook to build automated validation tools that scan the file before a commit goes live.

: Because Git shows you exactly what is being committed in the commented section of the file, it acts as a final "sanity check." If you see a file in that list that shouldn't be there, you can close the editor without saving to abort the commit and fix your staging area. Better Context This public link is valid for 7 days

This happens frequently when using GUI editors like VS Code. The terminal pauses, waiting for you to close the tab. If you accidentally close the terminal or freeze the process, Git leaves a lock file behind.
