A project’s working directory often contains a number of files you’d rather not save in your repository and share with others.
Some examples of these might be:
node_modules
).vendors
).You can exclude these files by not adding them to the staging area when you commit however it’s easy to forget to do that, and the files still be displayed when you run git status
.
To avoid having to ignore unwanted files manually, you can create a .gitignore
file in the working directory of your project. Inside this file, you can specify simple patterns that Git will use to determine whether or not a file should be ignored.
Let’s say you have the following directory tree:
.
├── README
├── config.env
├── foo
│ ├── config.env
│ └── bar.php
└── index.php
If you wanted to ignore all the config.env
files, you just need to enter:
config.env
With this pattern, both of these files would be ignored:
config.env
foo/config.env
To just ignore the config.env
in the root directory, you can prefix the pattern with a forward slash, just like this:
/config.env
Want to ignore all of the PHP files in your project? This pattern will do that for you:
*.php
The process for ignoring folders is very similar. Just enter the name of the folder:
vendors
With this pattern, Git won’t just ignore vendors
in the root directory. Any subdirectories named vendors
will be ignored as well.
If they existed, these directories would also be ignored:
/applications/vendors
/vendors
/app/vendors/
Although you don’t need to, I’d recommend appending a forward slash to the end of every directory in your .gitignore
file.
There are two reasons for doing this:
vendors
and a directory called vendors
, using a slash will ensure that only the directory is ignored.Just like with files, you can tell Git to ignore just the vendors
directory in the root of your project by adding a forward slash to the beginning of the pattern:
/vendors/
Perhaps you’ve decided that you want to ignore every PHP file in your project, however you’d like to keep config.php
in the root of your working directory.
All you need to do is add !
to the beginning of the pattern:
# Ignore all PHP files
*.php
# Keep the home page
!/config.php
Any blank lines in .gitignore files are ignored by Git. Though if you would like to use comments you can start the line with #
.
