运行后自动登录到多台服务器上执行程序

#!/usr/bin/expect -f

set ipaddress [lindex $argv 0]
set passwd [lindex $argv 1]
set timeout 30
spawn ssh root@$ipaddress

#expect "yes/no"
#send "yes\r"

expect "password:"
send "$passwd\r"
expect "]*"
send "mkdir -p /tmp/haha/haha2\r"
send "exit\r"

 

***************

expect {
"(yes/no)?" {
     send "yes\n"
  }
"password:" {
   ....
}




判断语句

if {$havepass == 0} {
  expect "password:" { send "$pw\n" }
}

 

或者：

 

expect {
"yes/no" { send "yes\r"; exp_continue}
"password:" { send "$passwd\r" }
}
