建立一csv檔, 兩個欄位如下

5101,532
5102,592
5103,321

第一欄為帳號使用班級加座號, 第二欄為密碼

建立學生群組

groupadd students

mkdir -p /home/students/111/5/

#!/bin/bash

class="5";
csv="${class}.csv"; 

while IFS="," read -r seatno passwd
do
  user="$seatno";
  home="/home/students/111/$class/$user";


  #if [ ${#user} > 3 ]
  #then
	  echo "user: $user"
	  echo "passwd: $passwd"
	  echo "home: $home"
	  useradd $user -g students -m -d $home -s /sbin/nologin;
	  echo -e "$passwd\n$passwd" | passwd $user 
	  echo -e "$passwd\n$passwd" | smbpasswd -s -a $user 
	  echo "$user created";

  #fi

done < <(tail -n +1 $csv)
