expect 批量修改服务器用户密码

每个技术人员离职，留下的人 就要修改他的服务器账号密码，很麻烦，故写次脚本偷懒

change.sh 如下

#!/bin/bash
for  i  in  ` awk  '{print $1}'  account.txt`
do
 j=` awk  - v  l= "$i"  { if (l==$1)print $2} account.txt`
 a=` awk  - v  l= "$i"  { if (l==$1)print $3} account.txt`
 b=` awk  - v  l= "$i"  { if (l==$1)print $4} account.txt`
 c=` awk  - v  l= "$i"  { if (l==$1)print $5} account.txt`
 d=` awk  - v  l= "$i"  { if (l==$1)print $6} account.txt`
expect login.exp $i $j $a $b $c $d
done

login.exp 如下

#!/usr/bin/expect -f
set  ip [lindex $argv 0]
set  user [lindex $argv 1]
set  passwd  [lindex $argv 2]
set  newpasswd [lindex $argv 3]
set  rootpasswd [lindex $argv 4]
set  newrootpasswd [lindex $argv 5]
spawn  ssh  $user@$ip
expect {
        "yes/no"  {send  "yes\r" ;exp_continue}
        "password:" {send  "$passwd\r" }
}
expect  "]$"
send  "password $user"
expect {
        "password"  {send  "$newpasswd\r" ;exp_continue}
        "password"  {send  "$newpasswd\r" }
}
expect  "]$"
send  "su root\r"
expect  "password"
send  "$rootpasswd\r"
expect  "]#"
send  "password root"
expect {
        "password"  {send  "$newrootpasswd\r" ;exp_continue}
        "passwrod"  {send  "$newrootpasswd\r" }
}
expect  "]#"
send  "exit\r"

account.txt 格式如下

ip user  passwd  newpasswd rootpasswd newrootpasswd
