Remove git configuration

Remove git configuration

As one of the most popular version control systems currently, Git plays an important role in development. However, in some cases, we may need to remove the git configuration, such as deleting old version records in the project to reduce file size, or deleting sensitive information in the project to ensure security.

Here are two methods to remove git configuration.

Method 1: Use the git filter-branch command

1. Create a new branch

We first need to create a new branch to modify the history of the Git warehouse Record. Open Git Bash, go into the current project's folder, and enter the following command:

$ git checkout --orphan new_branch

This will create a new branch named "new_branch", which does not have a commit history at this time.

2. Use the filter-branch command

Use git's filter-branch command to modify the history records in the Git repository.

For example, to delete all history records of a specific file (file.txt) in the project, you can use the following command:

$ git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch file.txt' --prune-empty --tag-name-filter cat -- --all

This command will delete all history records of "file.txt" , and create a new Git repository history.

3. Clear the cache and push to the remote warehouse

After completing the above steps, we need to push the modifications on the new branch to the remote warehouse. Enter the following command:

$ git rm -rf .git/refs/original/ && 
git reflog expire --expire=now --all && 
git gc --prune=now && 
git push origin --force --all

Now, your Git repository has been stripped of all history for the specific file. However, it should be noted that this method may cause some branches of the Git warehouse to be cleared. It is recommended to use it after backing up the data.

Method 2: Use the BFG Repo-Cleaner tool

BFG ​​Repo-Cleaner is an open source Git warehouse cleaning tool that can be used to delete sensitive data or reduce the size of the Git warehouse. Here is a brief introduction on how to use BFG Repo-Cleaner to remove Git configuration.

1. Download and install the BFG Repo-Cleaner tool

Enter the following command in the terminal to download the BFG Repo-Cleaner tool:

$ wget http://repo1.maven.org/maven2/com/madgag/bfg/1.13.0/bfg-1.13.0.jar

Then bfg -1.13.0.jar file is copied to the current project's folder.

2. Run BFG Repo-Cleaner

Use the following command to run the BFG Repo-Cleaner tool:

$ java -jar bfg-1.13.0.jar --delete-files *.txt

This command will delete all files with " *.txt" file.

3. Clear the cache and submit the changes

Run the following command, clear the cache and submit the changes:

$ git reflog expire --expire=now --all && 
git gc --prune=now --aggressive

Now, our Git repository has removed the sensitivity Data, modifications can be pushed to the remote warehouse.

Summary

Removing Git configuration can reduce the size of the Git warehouse or delete sensitive data, which is very helpful for maintaining and managing Git warehouses. This article introduces two methods to remove Git configuration, but it should be noted that you must back up the data before making any modifications to ensure data security.
