用户权限

sudo免密码:

    echo "$USER ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/$USER

增加用户:

    adduser git # 已经处理好了一下依赖
    mkdir /home/git

删除用户: deluser git
添加组:

    sudo usermod -aG docker wang
    sudo usermod -aG sudo wang  // 允许wang执行sudo命令

查看uid, gid

$ whoami
wangx
$ id wangx
uid=1000(wangx) gid=1001(wangx) 组=1001(wangx),998(wheel),991(lp),3(sys),90(network),98(power),1000(autologin),965(docker)
