批量管理Git项目脚本

发表于 | 分类于 | 浏览量:

应用场景: 本地clone有多个git项目，日常维护需要经常修改，又不想每次切换目录，然后pull、push代码…

使用方法:

  1. 创建shell脚本gghelp.sh

  2. 添加alias

    echo "alias gg='~/gghelp.sh'" >> ~/.bashrc

  3. 防止误删除

    sudo chattr +ae gghelp.sh

  4. 用法说明执行gg -x即可查看

    $ gg -x
        Usage: gghelp.sh [-a --add] [-c --commit] [-d --diff]
                         [-e --epush] [-p --pull] [-s --status]

        Options:
            -a|--add    execute git add --all
            -c|--commit execute git commit
            -d|--diff   execute git diff
            -e|--epush  execute git push
            -p|--pull   execute git pull
            -s|--add    execute git status (default option)

以下为gghelp.sh内容:
