expect 脚本

1、ftp登录远程服务器

#!/usr/bin/expect -f 

spawn ftp 192.168.250.12

expect "Name (192.168.250.12:root):" { send "root\r"}

expect "Password:" { send "cmcc\r" } 

expect "ftp>" {send "binary\r"}

expect "ftp>" {send "get anaconda-ks.cfg\r"}

expect "ftp>" {send "exit\r"}

2、ssh到远程机器并交互式输入命令后退出

#!/usr/bin/expect -f 

if { $argc != 2 } {

   puts "args error!for example:expect ssh.expect user ip"

   exit

}

set user [lindex $argv 0] 

set ip [lindex $argv 1]

set passwd [lindex $argv 2]

spawn ssh -l $user $ip 

expect { 

"*yes/no" {send "yes\r";exp_continue}

"*password:" {send "cmcc\r";exp_continue}

"#*" {send "mkdir -p /opt/test1\r" }

}

send "exit \r"

#interact    ##交互式命令，如果有此参数，脚本退出，但是窗口不退出，可以直接在远程机上输入命令

expect eof

3、匹配任意条件后输入对应的结果

#!/usr/bin/expect -f

expect {

"hi" { send "you said hi\n"}

"hello" {send "you said hello\n"}

"word" {send "you said word\n"}

}
