Question

我正在使用期望运行一个bash脚本，其中ssh为5个盒子，运行aptitude dist-upgrade -d，拉上包，然后将它们scra回原始盒子。

所有方框都有相同的密码，所有方框都需要输入“y”才能对dist-upgrade说“是”。

我目前期望的剧本很长而且很乱，有大量的以下重复

## Original box
expect "password"
send "Password\n"
## Box sshing to
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"

我的问题是，我如何“重复”这一点，以便在密码被要求的地方发送密码，并且在要求继续提示的地方，它发送y。因此，我不必得到将要发生的事情的完美顺序（有时候，我必须发送“是”的混合密钥检查）

以下完整脚本：

#!/usr/bin/expect -f
set timeout -1
## This uses manualpatching.sh, used to zip up a list of the latest Debian packages
spawn ./manualpatching.sh
## BOX1
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
## BOX2
expect "password"
send "Password\n"
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
expect "password"
send "Password\n"
expect "connecting"
send "yes\n"
## BOX3
expect "password"
send "Password\n"
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
expect "password"
send "Password\n"
## BOX4
expect "password"
send "Password\n"
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
expect "password"
send "Password\n"
## BOX5
expect "password"
send "Password\n"
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
expect "password"
send "Password\n"
## BOX6
expect "password"
send "Password\n"
expect "password"
send "Password\n"
expect "want to continue?"
send "y\n"
expect "password"
send "Password\n"
## END
expect eof

感谢Gaurav指出我正确的方向。

我使用exp_continue缩小了我的脚本，现在它更干净，更通用：

#!/usr/bin/expect -f
set timeout -1
spawn ./manualpatching.sh
expect {
      "Are you sure you want to continue connecting (yes/no)" {
            send "yes\r"
            exp_continue
      }
      "password" {
            send "Password\r"
            exp_continue
      }
      "want to continue?" {
            send "y\r"
            exp_continue
      }
}

如何在没有长脚本的情况下对重复案例使用expect？
