創建一個shell腳本來安裝更新基於一些額外的研究和低於百勝答案

Question

OK，這是我想我的腳本做什麼：

1. 提取更新
2. 安裝的更新特定的順序
3. 等待幾秒鐘，百勝完成更新每個部分
4. 重新設置root帳戶密碼（我怎麼硬編碼或通過腳本設置？）
5. 重置ssh帳號密碼（該怎麼辦我硬編碼或通過腳本設置？）
6. 清除歷史記錄
7. 刪除文件

8. 提示重新啓動

   #!/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
