This is faster as you don't have to checkout each revision before running the filter. The -cached option removes a file from the index not the disk. The -index-filter option modifies a repo's staging (or index). Git filter-branch -index-filter 'git rm -cached -ignore-unmatch pathname' commitHASH For example, a filter can remove a file from every indexed commit. You can pass this command a filter for rewriting the Git index. The emojis.jar is a candidate for removal. The aui-dependencies.jar compacts to 169KB but the emojis.jar compacts only to 580. The pack size column is the most relevant. The BFG is specifically designed for removing unwanted data like big files or passwords from Git repos, so it has a simple flag that will remove any large historical (not-in-your-current-commit) files: '-strip-blobs-bigger-than'Īll sizes are in kB's. Remember, after you rewrite the history, whether you use the BFG or filter-branch, you will need to remove reflog entries that point to old history, and finally run the garbage collector to purge the old data. Git filter-branch - powerful, tricky to configure, slow on big repositories. The BFG Repo Cleaner - fast, simple, easy to use. There are two automated tools for doing this: Rewriting repository history is a tricky business, because every commit depends on it's parents, so any small change will change the commit id of every subsequent commit. In order for that to be useful, we need to rewrite all Git repository history that contained the unwanted file, so that it no longer references it - git gc will then be able to discard the now-unused data. Git 'gc' (garbage collection) will remove all data from the repository that is not actually used, or in some way referenced, by any of your branches or tags. Repack the repository, garbage-collecting the now-unused data using git gc Remove all reflog history that refers to the old commit history Remove the file from repository history - rewriting Git history, deleting the file from all commits containing it Remove the file from your project's current file-tree To remove this file from your repository you must: Even if a user ends up removing the file from the project with a subsequent commit, the file still exists in the repository history. If a user commits a huge file, such as a JAR, every clone thereafter includes this file.

#Git branch rm code#

Recall that cloning a repository clones the entire history - including every version of every source code file.

Understanding file removal from Git history Make sure everyone has checked in their code and have agreed to cease development during maintenance. Keep in mind that maintenance can be disruptive to repository users. It is a good idea to communicate repository maintenance with the members of your workspace or repository followers. With the backup, if you accidentally corrupt a key element of your repo during maintenance, you can recover.

#Git branch rm zip#

The easiest way to create a backup is to clone your repository using the -mirror flag, and zip the whole clone. Make sure you read carefully and backup your repository before starting. The procedure and tools on this page use advanced techniques that involve destructive operations. This page focuses on removing large files from a Git repo and contains the following topics: If you imported from another version control system, you may need to clean up unnecessary files after the import. Maintenance of your Git repository typically involves reducing a repository's size.
