What Is a .gitignore File?

A .gitignore file tells Git which files and directories to intentionally ignore and not track in version control. It uses pattern matching to exclude build artifacts, dependency folders, IDE configuration files, secrets, and other files that should not be committed to a repository.

Without a proper .gitignore, repositories quickly become cluttered with generated files, binary artifacts, and potentially sensitive information like API keys and database credentials.

.gitignore Pattern Syntax

Pattern	Meaning	Example
`*`	Matches any characters except `/`	`*.log` ignores all log files
`**`	Matches directories at any depth	`**/build` ignores `build` folders anywhere
`?`	Matches any single character	`?.txt` matches `a.txt` but not `ab.txt`
`/` prefix	Anchors to the repository root	`/dist` ignores only the root `dist` folder
`/` suffix	Matches directories only	`logs/` ignores the `logs` directory
`!`	Negation — re-includes a previously ignored file	`!important.log`

Frequently Asked Questions

Can I have multiple .gitignore files?

Yes. Each directory in a repository can have its own .gitignore that applies to files within that directory and its subdirectories. There is also a global .gitignore for user-specific ignores (configured via git config --global core.excludesFile).

Why is my file still tracked after adding it to .gitignore?

.gitignore only prevents untracked files from being added. If a file was already committed, you must remove it from tracking with git rm --cached filename before the ignore rule takes effect.
