我是期望脚本的新手。我正在尝试使用自动 telnet 脚本备份华为路由器配置。我被困在处理一个字符串“---More---”,就像按任意键继续我想发送“\n”

我的路由器输出如下:

--------------------------------
-----------------------
voice-vlan mac-address 00d0-1e00-0000 mask ffff-ff00-0000 description Pingtel phone
voice-vlan mac-address 00e0-7500-0000 mask ffff-ff00-0000 description Polycom phone
voice-vlan mac-address 00e0-bb00-0000 mask ffff-ff00-0000 description 3com phone
#
---- More ----

我的脚本是:

#!/usr/bin/expect
spawn telnet 192.168.xx.xx
expect "Username:"
send "username\n"
expect "Password:"
send "password\n"
expect ">"
# 'dis cur' is like cisco's 'show run'
send "dis cur\n"
expect "---- More ----"
send "\n"
interact

在运行脚本终端时向我抛出此错误:

  bad flag "---- More ----": must be -glob, -regexp, -exact, -notransfer, -nocase, -i,      -indices, -iread, -timestamp, -timeout, -nobrace, or --
while executing
"expect "---- More ----""

任何人都可以帮助解决这个问题吗?...在​​此先感谢:)

快速回答:放在-ex以 a 开头的字符串前面,-以便期望代码可以确定它不是一个选项。

但是,除了快速回答之外,您还应该做一个更复杂的版本:

expect {
    ">" {
        # Found prompt
    }
    -ex "---- More ----" {
        send "\n"    ;# Or maybe \r?
        exp_continue ;# Keep on expecting please
    }
}
interact

这具有允许寻呼机输出出现零次、一次或多次的优点。
