课时1 初识Shell脚本

一、创建第一个Shell脚本

清理任务过程

1. 添加一个名为zhangsan的用户

useradd zhangsan

2. 将用户zhangsan的口令设置为123456

echo 123456 | passwd --stdin zhangsan

完善文件结构

\#！/bin/bash

echo "正在创建用户账号..."

userad zhangsan

echo "正在设置用户密码..."

echo 123456 | passwd --stdin zhangsan

echo "创建成功"

二、 执行Shell脚本

<table style="font-size:undefined; border-collapse:collapse; margin-top:10px; margin-bottom:10px; font-family:微软雅黑; width:599px"> 
 <tbody style="background-color:inherit"> 
  <tr style="background-color:inherit"> 
   <td style="word-break:break-all; border:1px solid rgb(153,153,153); padding:5px 10px; min-height:25px; min-width:25px; height:25px; background-color:inherit; width:106px"> 方法一</td> 
   <td style="word-break:break-all; border:1px solid rgb(153,153,153); padding:5px 10px; min-height:25px; min-width:25px; height:25px; background-color:inherit; width:451px"> 
    <div style="min-width:2px; background-color:inherit">
      chmod +x uad.sh 
    </div> 
    <div style="min-width:2px; background-color:inherit">
      sh ./uad.sh 
    </div> </td> 
  </tr> 
  <tr style="background-color:inherit"> 
   <td style="word-break:break-all; border:1px solid rgb(153,153,153); padding:5px 10px; min-height:25px; min-width:25px; height:25px; background-color:inherit; width:106px"> 
    <div style="min-width:2px; background-color:inherit">
      方法二 
    </div> </td>

    <div style="min-width:2px; background-color:inherit">
      sh uad.sh 
    </div> </td> 
  </tr> 
  <tr style="background-color:inherit"> 
   <td style="word-break:break-all; border:1px solid rgb(153,153,153); padding:5px 10px; min-height:25px; min-width:25px; height:25px; background-color:inherit; width:106px"> 
    <div style="min-width:2px; background-color:inherit">

    <div style="min-width:2px; background-color:inherit">
      source uad.sh

  </tr> 
 </tbody> 
</table>
