expect 非交換式 命令 expect 非交換式命令
測試實例：非交換式登陸某一臺服務器，通常第一次登陸一臺服務器的時候，需要按一下yes，然後再輸入密碼，我們目的是通過expect模擬輸入
[root@localhost ~]# ssh 10.3.151.31 The authenticity of host ‘10.3.151.31 (10.3.151.31)‘ can‘t be established. RSA key fingerprint is 08:1e:93:79:5c:0f:6c:de:68:d5:e8:57:8c:44:a5:57. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘10.3.151.31‘ (RSA) to the list of known hosts.

1、安裝expect
yum -y install expect2、編寫test.exp文件
#!/usr/bin/expect
set host [lindex $argv 0]
set password "kang"
spawn ssh "kang@$host"
expect {
"yes/no" {send "yes\r";exp_continue}
"*password" {send "$password\r"}
}
expect eof3、運行test.exp文件
[root@localhost ~]# expect test.exp 10.3.151.31 spawn ssh [email protected] [email protected]‘s password: [kang@localhost ~]$
