如何截断git历史记录:

#!/bin/bash
git checkout --orphan temp $1
git commit -m "Truncated history"
git rebase --onto temp $1 master
git branch -D temp

Here $1 is SHA-1 of the commit you want to keep and the script will create new branch that contains all commits between $1 and master and all the older history is dropped. Note that this simple script assumes that you do not have existing branch called temp. Also note that this script does not clear the git data for old history. Run git gc --prune=all && git repack -a -f -F -d after you've verified that you truly want to lose all history. You may also need rebase --preserve-merges but be warned that the git implementation of that feature is not perfect. Inspect the results manually if you use that.

如果你想保留上游存储库的完整历史，但本地签出较小，使用git clone——depth=1 [repo]进行浅克隆。

在执行提交后，您可以执行

Git fetch——depth=1来删除旧的提交。这使得旧的提交及其对象不可访问。 Git reflog expire——expire-unreachable=now——all。使所有旧提交及其对象过期 Git gc—aggressive—prune=全部删除旧对象

参见如何在提交后删除本地git历史记录。

注意，您不能将这个“浅”存储库推到其他地方:“不允许浅更新”。在更改Git远程URL后，请参阅远程拒绝(不允许浅更新)。如果你想做到这一点，你必须坚持嫁接。

如果你想在你的git repo中释放一些空间，但不想重新构建所有的提交(rebase或graft)，并且仍然能够从拥有完整repo的人那里推/拉/合并，你可以使用git clone shallow clone(——depth参数)。

; Clone the original repo into limitedRepo
git clone file:///path_to/originalRepo limitedRepo --depth=10

; Remove the original repo, to free up some space
rm -rf originalRepo
cd limitedRepo
git remote rm origin

你可以通过以下步骤来降低你现有的回购:

; Shallow to last 5 commits
git rev-parse HEAD~5 > .git/shallow

; Manually remove all other branches, tags and remotes that refers to old commits

; Prune unreachable objects
git fsck --unreachable ; Will show you the list of what will be deleted
git gc --prune=now     ; Will actually delete your data

如何删除所有git本地标签?

Ps:旧版本的git不支持从/到浅回购的克隆/推/拉。

根据BFG工具的Git repo，它“像Git -filter-branch一样删除大的或麻烦的blobs，但更快——并且是用Scala编写的”。

删除git数据，rm .git git init 添加一个git远程 力推动

这种方法简单易懂，效果良好。脚本的参数($1)是一个引用(标签，散列，…)，指向您想要保存历史记录的提交。

#!/bin/bash
git checkout --orphan temp $1 # create a new branch without parent history
git commit -m "Truncated history" # create a first commit on this branch
git rebase --onto temp $1 master # now rebase the part of master branch that we want to keep onto this branch
git branch -D temp # delete the temp branch

# The following 2 commands are optional - they keep your git repo in good shape.
git prune --progress # delete all the objects w/o references
git gc --aggressive # aggressively collect garbage; may take a lot of time on large repos

注意，旧的标签将仍然存在;因此，您可能需要手动删除它们
