如何在git中找到空的分支和标签 [英] How to find empty branches and tags in git
问题描述
我已经迁移了一个大型的svn存储库,其中包含数百个分支和标签,将它们拆分为多个存储库,现在我要检查在这些存储库中是否有任何空*分支/标记应删除,然后再推送实时迁移.
I've migrated a big svn repository with hundreds of branches and tags, split them into multiple repositories and now i'm looking to check if there are any empty* branches/tags in these repositories that should be deleted before pushing the migration live.
有比找到每个存储库并检出每个分支更快的方法吗?
Is there a faster way to find this than having to go to every repository and checkout every branch ?
*就此问题而言,空分支"或空标记"是指指向不包含任何文件的提交的分支或标记.
*For the purpose of this question, "empty branch" or "empty tag" means a branch or tag that points to a commit that contains no files.
推荐答案
使用您选择的编程语言为每个分支和标签运行git ls-tree <branch/tag> | wc -l
,并检查0
.您可以使用git branch
获取分支列表,并使用git tag
获取标签列表.
Run git ls-tree <branch/tag> | wc -l
for every branch and tag using the programming language of you choice and check for 0
. You get a list of branches with git branch
and a list of tags with git tag
.
这是一个使用bash的分支的简单示例:
Here is a simple example for branches using bash:
#!/bin/bash
for branch in $(git branch | cut -c 3-)
do
if [ $(git ls-tree $branch | wc -m) -eq 0 ]
then
echo "branch $branch is empty"
fi
done
