Gitignore

Gitignore

The .gitignore file is a text file that tells Git which files or folders to ignore in a project.

A local .gitignore file is usually placed in the root directory of a project. You can also create a global .gitignore file and any entries in that file will be ignored in all of your Git repositories.

To create a local .gitignore file, create a text file and name it .gitignore (remember to include the . at the beginning). Then edit this file as needed. Each new line should list an additional file or folder that you want Git to ignore.

The entries in this file can also follow a matching pattern.

  • * is used as a wildcard match
  • / is used to ignore pathnames relative to the .gitignore file
  • # is used to add comments to a .gitignore file

This is an example of what the .gitignore file could look like:

# Ignore Mac system files
.DS_store

# Ignore node_modules folder
node_modules

# Ignore all text files
*.txt

# Ignore files related to API keys
.env

# Ignore SASS config files
.sass-cache

To add or change your global .gitignore file, run the following command:

git config --global core.excludesfile ~/.gitignore_global

This will create the file ~/.gitignore_global. Now you can edit that file the same way as a local .gitignore file. All of your Git repositories will ignore the files and folders listed in the global .gitignore file.
