Question

问题是命令send＆＃34; xxxxx＆＃34;只是不发送。该命令似乎完全被忽略了。

在下面的脚本中，我可以登录服务器，但不再向服务器发送发送命令。

最后有一个输出示例。

超时陷阱用于调试。

#!/usr/bin/expect -f
##  getver_t.sh - Use telnet to get ver from Cisco devices
##  Could be asked for login ID or just pasword

set pass {Password1 Pass2}
set index 0
set timeout 5
set host [lindex $argv 0 ]

spawn ssh -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null admin@$host
expect {
"assword:" {
    send_user "\n--- sending [lindex $pass $index] ---\n"
    send "[lindex $pass $index]\r"
    incr index
    exp_continue
}
"\>" {
    send_user "\n--- I see a prompt ---\n"
    send -- "ter len 0\r"
    sleep 3
    send -- "show inv\r"
    sleep 3
    send -- "show ver\r"
    send_user "\n--- Time to end ---\n"
    sleep 3
    send -- "exit\r"
    sleep 3
    exit
}
timeout {
    send -- "\r"
    set timeout 5
    send_user "\n--- TIMED OUT 1 ---\n"
    send -- "ter len 0\r"
    sleep 3
    send -- "show inv\r"
    sleep 3
    send -- "show ver\r"
    sleep 3
    send -- "exit\r"
    sleep 3
    exit
}
}

send_user "\n--- out side land ---\n"
send "\r"
expect {
timeout {
    send_user "\n--- TIMED OUT 2 ---\n"
}
}

这就是我看到的运行脚本。

$ ./getver_s.sh server1
spawn ssh -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null admin@server1
Warning: Permanently added 'server1,10.1.1.3' (RSA) to the list of known hosts.
Password:
--- sending Password1 ---

Password:
--- sending Pass2 ---

------------------------------------------------------------
Welcome to server1

------------------------------------------------------------


server1>
--- I see a prompt ---

--- Time to end ---
$

我看到＆＃34; ---我看到了一个提示---＆＃34;和＆＃34; ---时间结束---＆＃34;消息但send_user命令之间的send命令不会发送到服务器。

我已经重写了这个脚本改变了逻辑并将其从不同版本的服务器（Debian7＆amp; 8）中运行，但结果始终是相同的。

为什么那些发送命令没有被发送？

添加了期望-d输出

期望发送命令不发送 - 在脚本期间停止发送
