用expect腳本執行命令
#!/usr/bin/expect #set user [lindex $argv 0] set user root set host 192.168.1.120 #set host [lindex $argv 1] set passwd "8023jun12" spawn ssh $user@$host expect "password:" send "$passwd\r" #interact expect "]*" send "w\r" interact #expect "]*" #send "exit\r"
執行過程：
[root@slave expect]# ./expect.exp spawn ssh [email protected] [email protected]'s password: Last login: Tue Dec 27 09:39:52 2016 from slave [root@master ~]# w 09:41:30 up 3:01, 2 users, load average: 0.00, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 192.168.1.107 06:41 2:19 0.03s 0.03s -bash root pts/1 slave 09:41 0.00s 0.00s 0.00s w [root@master ~]#

用expect腳本搭建一個創建文件系統：
有三個文件：
expect.exp文件用來存放expect腳本：
user：腳本用來存放用戶和對應的ip地址
touch.sh: 用來實際執行：
腳本具體代碼如下：
cat expect.exp #!/usr/bin/expect set user [lindex $argv 0] set host [lindex $argv 1] set passwd "8023jun12" set timeout 60 spawn ssh $user@$host expect "password:" send "$passwd\r" expect "]*" send "touch 12\r" expect "]*" send "exit\r"
cat user root:192.168.1.120 root:192.168.1.121
cat touch.sh
#!/bin/bash
#在服務器中創建一個文件12
[ -x expect.exp ] || chmod +x expect.exp
for i in `cat user`; do
username=`echo $i |awk -F":" '{print $1}'`
hostip=`echo $i |awk -F":" '{print $2}'`
./expect.exp $username $hostip
done運行的時候直接執行touch.sh腳本即可，不過三個腳本要放在同一目錄下面：
sh touch.sh
