批量删除久未使用的git分支
该脚本实现批量删除指定日期内久未删除的分支：
快捷使用
./git-cleanup.sh -d 90(天数)自定义保护分支列表
创建保护分支列表文件：
echo -e "production\nlegacy-system" > ~/.git_cleanup_protected指定自定义配置文件：
./git-cleanup.sh -c ./project_protected_branches.cfg -d 60配置文件格式说明：
- 每行一个分支名称
- 支持行末注释（以 # 开头的内容）
- 自动忽略空行和空格
查看当前保护分支列表
# 使用示例 $ ./git-cleanup.sh -l 当前受保护分支列表： ---------------------------------------- 分支名称 来源 ---------------------------------------- production [配置文件] /home/user/.git_cleanup_protected main [系统默认] master [系统默认] develop [系统默认] ---------------------------------------- （配置文件路径: /home/user/.git_cleanup_protected）
