创建一个shell脚本来安装更新

Question

根据一些额外的研究和下面的yum答案，这是我希望我的脚本要做的事情：

1. 提取更新
2. 按特定顺序安装更新
3. 等待几秒钟，以便为每个部分完成yum更新
4. 重设root帐户密码（如何通过脚本进行硬编码或设置？）
5. 重置ssh帐户密码（如何通过脚本进行硬编码或设置？）
6. 清除历史
7. 删除文件

8. 提示重新启动

   #!/bin/sh
   # Run as root
   
   # This extracts the tar copied to the server
   tar -xf updates
   sleep 5
   tar -xf app
   sleep 2
   
   # This moves to the February updates and install it.
   cd /updates/feb
   yum -y update *.rpm
   sleep 5
   # This moves to the March updates and install it.
   cd /updates/mar
   yum -y update *.rpm
   sleep 5
   # This moves to the April updates and install it.
   cd /updates/apr
   yum -y update *.rpm
   sleep 5
   # This moves to the May updates and install it.
   cd /updates/may
   yum -y update *.rpm
   sleep 5
   # This moves to the June updates and install it.
   cd /updates/june
   yum -y update *.rpm
   sleep 5
   # This moves to the August updates and install it.
   cd /updates/aug
   yum -y update *.rpm
   sleep 5
   # This moves to the September updates and install it.
   cd /updates/sep
   yum -y update *.rpm
   sleep 5
   # This moves to the APP dependencies and install it.
   cd /updates/app
   yum -y install *.rpm
   sleep 5
   # This resets the root password
   passwd root
   # This resets the ssh account password
   passwd ssh_user
   # This removes the files from the home directory
   cd /home/user
   rm -rf /updates
   wait 5
   # This clears the history and screen
   history -c
   clear
   # This reboots the server with a y/n prompt
   reboot

添加-y（告诉yum假设“是”答案），如下所示：

yum -y update *.rpm
