如何删除在 git 中错误提交的大文件

如何在 Git 中清除提交历史中的大文件

我做了件蠢事。假设我提交了一个100MB 的文件。然后我看到这个，删除这个文件，再次提交。这是删除文件的正常过程。

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.

如何最终删除该文件并节省磁盘空间？

您可以从 大卫 · 昂德希尔获取这个很棒的脚本，从 git 存储库中删除该文件:

#!/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

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

您可以使用 git filter-branch命令完成这项工作，如下所示:

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