# Gitのリポジトリがでかくなったときの削減の昔のやり方

## 方法1

`git verify-pack -v .git/objects/pack/pack-*.idx |sort -k 3 -n |tail -100`

`git rev-list --objects --all | grep xxx`

`git gc --prune=now --aggressive`

## 方法2

調べる

```
git rev-list --all --objects |     sed -n $(git rev-list --objects --all |     cut -f1 -d' ' |     git cat-file --batch-check |     grep blob |     sort -n -k 3 |     tail -n40 |     while read hash type size; do
echo -n "-e s/$hash/$size/p ";
done) |     sort -n -k1
```

削除する

```
git filter-branch -f  --index-filter 'git rm --force --cached --ignore-unmatch video/parasite-intro.avi'  -- --all
rm -Rf .git/refs/original
rm -Rf .git/logs/
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now
```

```
git count-objects -v
```
