总结：git 不常用命令

# 远程分支与本地分支有不相关的提交，合并远程分支
git pull origin main --allow-unrelated-histories

# 删除远程分之
git push origin --delete <branch_name>

# 更新远程分支列表
git remote update origin --prune

# 删除submodule

# Remove the submodule entry from .git/config
git submodule deinit -f .\3rd\xz-v5.8.1\

# Remove the submodule directory from the superproject's .git/modules directory
rm -rf .git/modules/3rd/xz-v5.8.1

# Remove the entry in .gitmodules and remove the submodule directory located at path/to/submodule
git rm -f 3rd/xz-v5.8.1
