簡(jiǎn)單模式：

#!/usr/bin/expect -f   set timeout 5   spawn ssh root@192.168.0.1expect "*assWord*"   send "root/r"   expect "#"   send "ifconfig /r"   expect eof

講解：

send：用于向進(jìn)程發(fā)送字符串expect：從進(jìn)程接收字符串 比如：expect "*assword*"spawn：?jiǎn)?dòng)新的進(jìn)程interact：允許用戶交互怎么使用變量：

#!/usr/bin/expect -fset port 22set user rootset host 192.168.0.12set password rootset timeout -1spawn ssh -D $port $user@$host "ifconfig"expect {  "*yes/no" { send "yes/r"; exp_continue}  "*assword:" { send "$password/r" }  }  expect "*#*"  send "ifconfig > /home/cfg /r"send "exit/r"}

講解：

expect {  "*yes/no" { send "yes/r"; exp_continue}  "*assword:" { send "$password/r" }  }  選擇模式，exp_continue表示繼續(xù)。通過(guò)讀取配置文件獲取變量：配置文件

192.168.0.1 root192.168.0.2 root

自動(dòng)化登錄腳本

#!/usr/bin/expect -fset f [open ./ip r]  while { [gets $f line ]>=0 } {       set ip [lindex $line 0]     set pwd [lindex $line 1]spawn ssh $ipexpect  "*password:" { send "$pwd/r" }expect "#"send "ifconfig /r"send "exit/r"interact}

講解：

可以多臺(tái)服務(wù)器循環(huán)執(zhí)行，是個(gè)非常使用的方式！

自動(dòng)化遠(yuǎn)程拷貝文件：

#!/usr/bin/expect -fset port 22set user rootset host 192.168.28.30set password rootset timeout -1spawn scp $host:/home/cfg ./expect {"*yes/no" { send "yes/r"; exp_continue}"*assword:" { send "$password/r" }}expect eof

講解：

原理和ssh一樣

遠(yuǎn)程執(zhí)行命令后寫(xiě)入文件，再通過(guò)scp到本機(jī)服務(wù)器：

#!/usr/bin/expect -fset port 22set user rootset host 192.168.28.30set password rootset timeout -1spawn ssh -D $port $user@$host "ifconfig"expect {"*yes/no" { send "yes/r"; exp_continue}"*assword:" { send "$password/r" }}expect "*#*"send "ifconfig > /home/cfg /r"send "exit/r"interactspawn scp $host:/home/cfg ./expect {"*yes/no" { send "yes/r"; exp_continue}"*assword:" { send "$password/r" }}expect eof
