让 telnet 在一行中执行单个命令 [英] let telnet execute single command in one line

问题描述

嘿，我可以使用telnet localhost 4242"登录到 telnet，现在我想执行一个命令show network".

hey i can login into telnet with "telnet localhost 4242" now i want to execute a single command "show network".

我怎样才能在一行中做到这一点?

How can i do this in one line ?

类似的东西

$ telnet localhost 4242 <-显示网络"

$ telnet localhost 4242 <- "show network"

哇这里是我想要的输出

推荐答案

I found expect 做我想做的事，等待某个输出然后采取行动:

I found expect to do exactly what i want, wait for a certain output and then act upon it:

expect << EOF
spawn telnet localhost 4242
expect -re ".*>"
send "show network\r"
expect -re ".*>"
send "exit\r"
EOF
