How to purge a huge file from commits history in Git?

I did a stupid thing. Imagine that I committed a 100MB file. Then I see this and delete this file and commit again. This is a normal procedure to delete a file.

But now the side effect is that my history is heavy because it's saved this large file (I believe this is why it is heavy). I am only using local git, so I do not synchronize in any server.

How can I definitively remove this file and save disk space?

Was it helpful?

Solution

You can do it using the git filter-branch command, like this :

git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch path_to_file" HEAD

OTHER TIPS

The command you are looking for is filter-branch. It allows you to permanently remove files from an enlistment. This blog has a great tutorial on how to remove problematic files from the repository

You can take this great script from David Underhill to remove the file from the git repository:

#!/bin/bash
set -o errexit

# Author: David Underhill
# Script to permanently delete files/folders from your git repository.  To use 
# it, cd to your repository's root and then run the script with a list of paths
# you want to delete, e.g., git-delete-history path1 path2

if [ $# -eq 0 ]; then
    exit 0
fi

# make sure we're at the root of git repo
if [ ! -d .git ]; then
    echo "Error: must run this script from the root of a git repository"
    exit 1
fi

# remove all paths passed as arguments from the history of the repo
files=$@
git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch $files" HEAD

# remove the temporary history git-filter-branch otherwise leaves behind for a long time
rm -rf .git/refs/original/ && git reflog expire --all &&  git gc --aggressive --prune
