Commit-editmsg

We have all been there. You spend 10 minutes writing a detailed, perfectly formatted commit message. You save and close the editor... but the commit fails.

Maybe you forgot to stage a file, or a pre-commit hook rejected the code.

Git aborts the process. Your terminal screams error. Is your message gone?

No. It is saved in .git/COMMIT_EDITMSG.

The Fix: Instead of rewriting the message, simply run:

git commit -F .git/COMMIT_EDITMSG

This tells Git: "Use the content of that file as the message and try again."

When you decide to edit a commit message, Git provides a file named COMMIT-EDITMSG for you to edit. This file contains the current commit message that you can modify. The process usually involves: COMMIT-EDITMSG

COMMIT_EDITMSG is a temporary file created by Git during the committing process. It resides in the .git directory of your project (at .git/COMMIT_EDITMSG).

Its primary purpose is to act as a staging ground for your commit message. When you run git commit (without the -m flag), Git opens this file in your default text editor, allowing you to write, review, and edit the message before the commit is finalized and saved to the database.

The COMMIT-EDITMSG is the quiet workhorse of Git. It is the bridge between your intent (the code change) and your legacy (the commit history). By ignoring it in favor of one-line shell commands, you are choosing convenience over clarity. You are depriving your future self and your teammates of crucial context.

Embrace the file. Learn its structure. Automate it with hooks. Scaffold it with templates. Enrich it with --verbose.

The next time you stage a set of changes, close your terminal, type git commit, and take 60 seconds to write a message inside that COMMIT_EDITMSG buffer. Look at the diff. Write a subject line. Write a body. Save. Close.

You won't just be making a commit. You'll be crafting a piece of your project’s story. And the humble COMMIT_EDITMSG is your pen. We have all been there

COMMIT_EDITMSG is a temporary file Git creates whenever you run git commit without a message (the -m flag). It acts as a workspace for you to draft, edit, and save your commit message before it's officially added to the project history. How it Works

Triggers: When you run git commit, Git opens your default text editor (like Vim, Nano, or VS Code) and displays this file.

Editing: You write your message at the top. Any lines starting with # are treated as comments and will be automatically stripped out by Git.

Saving: Once you save and close the file, Git reads the contents and completes the commit.

If you close the file without saving or leave it empty, the commit is usually aborted. Best Practices for Content

To keep your project history clean, follow the "50/72 rule": This tells Git: "Use the content of that

Subject Line: Keep the first line under 50 characters. It should be a concise summary of the change.

Body: Separate the subject from the body with a blank line. Keep body lines under 72 characters for readability in different terminal sizes.

Style: Use the imperative mood (e.g., "Fix bug" instead of "Fixed bug") and capitalize the first letter. Common Issues & Tips

If you set this to true, Git will always include the diff at the bottom of COMMIT_EDITMSG when you commit.

git config --global commit.verbose true

This is excellent for developers who prefer to verify exactly what they are committing while writing the message.
