应用要求：
    目标机172.25.254.1-172.25.254.10  
    主机上执行TNetUser.sh 会在目标机中建立namefile中的用户，密码存于passfile文件。
需要的文件
1.脚本文件：TNetUser.sh(主机运行文件),scp.exp(expect文件)
      
  (往目标机发送的文件)    Create_user.sh（执行文件）
              namefile（存储用户名文件）
                   passfile（存储密码文件）
(1)vim TNetUser.sh
#!/usr/bin/env tcsh
for NUM in {1..10}
do
ping -c1 -w1 172.25.254.$NUM > /dev/null && (
        /mnt/scp.exp /mnt/Create_user.sh/mnt/namefile /mnt/passfile 172.25.254.$NUM /mnt redhat | grep -E"^The|ECDSA|connecting|Warning|password|spawn" -v | sed"s/Permission\ denied\,\ Please\ try\ again\./172.25.254.$NUM password iserror/g"
)
done
(2)vim Create_user.sh
#!/usr/bin/env tcsh
        MAXUSER=`wc -l $1 | cut -d "" -f 1`
        MAXPASS=`wc -l $1 | cut -d "" -f 1`
                [ "$MAXUSER"-eq "$MAXPASS" ] &&(
                for NUM in $( seq 1$MAXUSER )
                do
                USERNAME=`sed -n ${NUM}p$1`
                PASSWORD=`sed -n ${NUM}p$2`
                CKUSER=`getent passwd$USERNAME`
                [ -z "$CKUSER"]&&(
                useradd $USERNAME
                echo $PASSWORD | passwd--stdin $USERNAME
                )||(echo "$USERNAMEexist")
                done
                )||(echo "Number ofusers and password number does not match")
(3)vim scp.exp
#!/usr/bin/expect

set NameFile [lindex $argv 1]
set PassFile [lindex $argv 2]
set Ip       [lindex $argv 3]

spawn scp $FileBash $NameFile $PassFile root@$Ip:$Dir
expect {
        "yes/no"
        {send"yes/r";exp_continue}
        "password:"
        {send "$Pass\r"}
        }

        }
