我怎样才能找到空的git提交？ [英] How can I find empty git commits?

问题描述

我可以使用哪些命令在git存储库中查找空提交，即将被 git filter-branch --prune-empty 删除的提交。 ？

What command(s) can I use to find empty commits in a git repository, i.e. the commits that would be removed by git filter-branch --prune-empty?

推荐答案

您希望排除无父级提交和合并提交，然后查看哪些树与父级具有相同的树。

You'd want to exclude parentless commits and merge commits, then see which ones have the same tree as their parent.

for sha in $(git rev-list --min-parents=1 --max-parents=1 --all)
do
   if [ $(git rev-parse ${sha}^{tree}) == $(git rev-parse ${sha}^1^{tree} ) ]
   then
       echo "${sha} will be pruned"
   fi
done
