Summary: Sometimes, we must put certain files into the Git working directory, but cannot submit them, such as the development environment automatically generates intermediate files and saves the configuration of the database password. document. However, git status will display multiple untracked files every time, which affects our use of Git.

Fortunately, Git has taken everyone's feelings into consideration, and the solution to this problem is very simple. Create a special .gitignore file in the root directory of the Git workspace , and then fill in the file names to be ignored, and Git will automatically ignore these files.

There is always a .gitignore hidden file in the root directory, and the function of this hidden file is not only to ignore the original rules, but also to make your own rules according to your own needs;

There is no need to write the .gitignore file from scratch. GitHub has prepared various configuration files for us. You only need to combine them to use them. All configuration files can be browsed directly online: https://github.com/github/gitignore

The principle of ignoring files is:

1. Ignore intermediate files, executable files, etc. generated by compilation , that is, if a file is automatically generated through another file, then there is no need to put the automatically generated file into the repository, such as the .class file generated by Java compilation;

2 , business data generated when the project is running, such as user thumbnails, user information, etc.;

3. Ignore your own configuration files with sensitive information, such as configuration files that store passwords

For example:

If we want to ignore .pyc, .pyo, dist and other files or directories generated by Python compilation, we can write the .gitignore file like this:

# Python:
*.py[cod]
*.so
*.egg
*.egg-info
dist
build
