shell脚本之批量添加用户

源码文件：add.sh

#!/bin/sh
groupadd users
   T_class=$1
   num_class=`expr $2 + 0`
       if (test $num_class -le 9)
       then
           num_class=$num_class
       fi
   max_stid=`expr $3`
   num_userid=1
   if [ ! -x /home/$1$num_class ]
       then
       mkdir /home/$1$num_class
   fi
   while (test $num_userid -le $max_stid)
   do
       if (test $num_userid -le 9)
           then
               num_userid="0"$num_userid
    else
    num_userid=$num_userid
       fi
user_name=$T_class$num_class$num_userid

   echo $user_name":"$user_name >> user_pwlist
   adduser -g users -d /home/$1$num_class/$user_name $user_name
   chmod 775 /home/$1$num_class/$user_name
num_userid=`expr $num_userid + 1`
done
chpasswd < user_pwlist
pwconv
rm user_pwlist -f

执行方法：./add.sh 110410 120 50
生成的效果就是：11041012001........11041012050
