Git is a powerful version control system, but sometimes we need to exclude certain files from being committed to keep our repository clean and optimized. One common type of file that you might want to exclude from git commit is obj files, which are intermediate files generated during the compilation of source code.

To exclude obj files from git commit, you can use the .gitignore file. This file allows you to specify patterns of files and directories that you want git to ignore. To exclude obj files, you can simply add a line in the .gitignore file that specifies the pattern for obj files. For example, you can add the following line to exclude all obj files in your repository:

*.obj

This line tells git to ignore any file with the .obj extension. If you want to exclude obj files from a specific directory, you can specify the path to that directory in the .gitignore file. For example, if you want to exclude obj files from a directory named 'build', you can add the following line in the .gitignore file:

build/*.obj

After adding the appropriate patterns to the .gitignore file, git will automatically exclude obj files from being committed. If there are already obj files that have been committed before, you can remove them from the repository using the git rm command. For example, to remove all obj files from the repository, you can run the following command:

git rm '*.obj'

After excluding obj files from the repository, it's important to remember to commit the changes to the .gitignore file. This ensures that the specified patterns will be applied to all future commits.

In addition to excluding obj files, you can also consider excluding other types of files that are generated during the build process, such as executables, libraries, and logs. By excluding these files from git commit, you can keep your repository clean, reduce its size, and improve its performance.

In conclusion, excluding obj files from git commit is a simple yet effective way to keep your repository clean and optimized. By using the .gitignore file and specifying the appropriate patterns, you can ensure that obj files are not included in your commits. This helps to streamline the development process and maintain a tidy and efficient repository.
