可以期望被告知不要在没有显式设置一个巨大的恒定值的情况下超时吗? [英] can expect be told not to timeout without explicitly setting a huge constant value?

问题描述

我已将超时设置为愚蠢的高数字.有没有更好的办法告诉脚本不要超时?

I've set the timeout to a stupid high number. Is there a better way to tell the script not to time out?

#!/usr/bin/expect
spawn telnet 10.10.10.10
set timeout 200000000
expect "login"
send "user\r"
expect "Password:"
send "password\r"
send "./run/this.sh\r"

推荐答案

将timeout值设置为-1

set timeout -1

expect的摘录， man page

An excerpt from the expect, man page

如果不使用超时关键字，则在超时时执行隐式null操作. 默认超时时间为10秒，但可以通过命令"set timeout 30"将其设置为例如30. 可以用值-1指定无限超时..

If no timeout keyword is used, an implicit null action is executed upon timeout. The default timeout period is 10 seconds but may be set, for example to 30, by the command "set timeout 30". An infinite timeout may be designated by the value -1.
