How to remove a file that has already been committed in git?

To remove files that have already been committed, you can use the git rm command. Here are some steps:

1. Make sure you are in your local Git repository directory.
2. Use the git rm command and include the filename of the file you want to delete.
3. Delete the file named <文件名> from the git repository.
4. For example, if you want to delete a file named example.txt:
5. remove example.txt from git
6. Submit the changes for deletion:
7. git commit -m “delete file example.txt”
8. Finally, push the changes to the remote repository.
9. push the changes to the git repository

Note: The above steps will delete all history of the file and remove it from the remote repository. If you only want to delete the file from the latest commit while keeping its history, you can use the git reset command to undo the latest commit. Please be cautious when using the git reset command as it will alter the repository’s history and may cause issues unless you are sure of what you are doing.
