What is a .gitignore file?

.gitignore tells Git which files or directories should not be version-tracked. It's commonly used to exclude build artifacts (node_modules, build), system files (.DS_Store), environment configs (.env), and IDE settings. Proper use of .gitignore keeps your repository clean.

How do I create a .gitignore file?

Create a plain text file named .gitignore in your project root directory. Each line contains one ignore pattern. Supports wildcards (*.log), directory names (node_modules/), comments (#), and negation patterns (!important.log). Use this generator to quickly create one.

Can .gitignore ignore files already tracked by Git?

No. Files already tracked by Git are not affected by .gitignore. To stop tracking a committed file, first remove it from version control with git rm --cached (keeping the file locally), then add the .gitignore rule.

What wildcards can I use in .gitignore?

* matches any string, ** matches nested directories, ? matches a single character, [abc] matches character sets. Examples: *.log matches all log files, build/** matches everything under the build directory, node_modules/ ignores the entire directory.
