Autoexpect 在脚本末尾挂起

我有一个自动预期脚本。我修改了它并且效果很好，但是当它完成运行时它会挂起，我需要执行 ctrl+C 才能获取我的终端

[..]
887VA#logout
Connection to 10.255.255.1 closed by remote host.
Connection to 10.255.255.1 closed.
root@blackbox:/etc/myscripts#

^Croot@blackbox:/etc/myscripts# ^C
root@blackbox:/etc/myscripts#

在上面的空白处我按了多次回车键

代码

#!/usr/bin/expect -f

set force_conservative 0  ;# set to 1 to force conservative mode even if
                          ;# script wasn't run conservatively originally
if {$force_conservative} {
        set send_slow {1 .1}
        proc send {ignore arg} {
                sleep .1
                exp_send -s -- $arg
        }
}

set timeout -1
spawn $env(SHELL)
match_max 100000


send -- "ssh [email protected]\r"
expect -exact "Password: "
send -- "passwordhere!!!\r"
expect -exact "887VA#"
send -- "show interface vlan 2\r"
expect -exact "Vlan2 is up, line protocol is up \r"
send -- "logout\r"
expect eof

您生成一个 shell，发送 ssh 命令，执行一些操作，然后注销 ssh 会话。你永远不会退出外壳。

我通常会编辑自动期望生成的脚本，以不生成 shell，而是实际生成我想要执行的操作。

简短的重写：

#!/usr/bin/expect -f
# default timeout is 10 seconds
spawn ssh [email protected]
expect -exact "Password: "
send -- "passwordhere!!!\r"
expect -exact "887VA#"
send -- "show interface vlan 2\r"
expect -exact "Vlan2 is up, line protocol is up \r"
send -- "logout\r"
expect eof

关于脚本的逻辑：如果线路协议是，您应该做什么不是向上？
