如果远程交换机在期望脚本中没有响应，如何继续下一个命令

Question

I'm passing the switch name from a bash script. The bash script iterates through a text file and sends the switch name. Sometimes if the switch is not responding, the expect script gets stuck. I want the script to wait for some time and move to next switch or at least come out. I have used the timeout but with no help.

set timeout 60
.
.
.
expect "*> "
send "ssh -l admin $switchName.XXX.XXXXXX.net switchshow -portname > $filename1\r"
sleep 2
expect {
        "*(yes/no)? " {
                send "yes\r"
                exp_continue
        }

        "*assword: " {
                send "$password\r"
        }
        default {
                exp_continue
        }
}

Any suggestion is appreciated.

you want to expect to see the "timeout" keyword:

expect {
        timeout {
                puts "timed out waiting for $switchName"
        }
        "*(yes/no)? " {
                send "yes\r"
                exp_continue
        }

        "*assword: " {
                send "$password\r"
                exp_continue
        }
        eof
} 

I also updated your conditions a bit so that you remain in the expect "loop" until the ssh command completes.
