How to delete a folder in git

Git is one of the most popular version control tools in modern development. It provides many conveniences and features for code management and team collaboration, allowing developers to easily manage and revise code. However, sometimes we need to delete certain files or folders. Deleting folders is not a simple thing in git and requires the use of some special commands.

Command to delete a folder in Git

To delete a folder in git, you can use the following command:

git rm -r folder_name

After executing this command, git will remove the folder from the index and delete it from the working directory. At this time, executing the git status command will show that the folder has been deleted.

However, deleting a folder does not completely remove it from git's history. This means that if you need to restore the folder in a subsequent version, you can do so.

To completely delete a folder and all its history, you can use the following command:

git filter-branch --tree-filter 'rm -rf folder_name' HEAD

Where the --tree-filter option tells Git to filter each commit (On the path from HEAD to the root) execute a command (in this case to delete the folder), rm -rf folder_name is a command to recursively delete the folder.

Note: Using filter-branchThis command will modify the Git history, so please make sure that if anyone else is sharing the repository with you, this should be negotiated.
