Bash Cisco Expect脚本中出现错误

我写了一个基本的Cisco expect脚本。ssh连接后，我想在从文件发送命令行时检测Cisco错误输出，例如：

SPAIN#sow crypto isakmp sa
       ^
% Invalid input detected at '^' marker.

我想在循环中捕获“%Invalid”，并停止程序

foreach line $data {
    expect "*#"
    send "$line\r"
    expect {
        "% Invalid*" { send_user "\n Command [ $line ] Failed. \n"; exit 252 }
    }

我在输出中得到以下错误：

SPAIN>enable
Password:
SPAIN#sow crypto isakmp sa
   ^
% Invalid input detected at '^' marker.

SPAIN#invalid command name "sow crypto isakmp sa"
while executing
"$line "
invoked from within
"expect {
     "% Invalid*" { send_user "\n Command [ $line ]  Failed. \n"; exit 252}
}"
("foreach" body line 4)
invoked from within
"foreach line $data {
    expect "*#"
    send "$line\r"
    expect {
        "% Invalid*" { send_user "\n Command [ $line ] Failed. \n"; exit 252}
    }
}"

谢谢

问题是[]在Tcl中有特殊的意义；执行命令并返回结果

更改此项：

expect {
    "% Invalid*" { send_user "\n Command [ $line ] Failed. \n"; exit 252 }
}

致：

有关更多信息，请参阅Tcl手册中的

expect {
    "% Invalid*" { send_user "\n Command \[ $line \] Failed. \n"; exit 252 }
}
