I am trying to write an expect script. Being a newbie in expect, maybee this is a silly doubt but i am stuck here.
So essentially , i want the o/p of one router command to be captured . Its something like this
My expect script looks something like this
Now, i see the complete o/p by the last statement. Not able to get the correct syntax of -re for parsing the o/p. Just want to store the variables
Input Rx and input bytes.
Any help is really appreciated.
Thanks,

Reason: Code tags
Please always use code tags when posting any code fragments or data samples. If you are not sure how to use code tags, then please have a look at this forum video tutorial
Can you please post expect o/p and what exactly do you want to extract from expect o/p in code tags.
and i want to write an expect script for login in the router, give the command to dislay these stats and then store them in the script variables to use them .
I am able to log-in the router and give the command but not able to use regex for parsing the expect_out buffer.
Any help is appreciated.
Thanks,

Of course the above is very dependant on your exact output and you may be best off playing around with a testing script to get the matching just right. Below is the script I used to test my posted solution, and you can see even without the device/server in question I can throw together some regex strings that match what you see comming from the device:

I'm using Expect to execute a command on a router and return the output to a file. The output is a list. At the end of the list there's a statement that reads, "Found 165 active connections" (Where "165" could be any number between 0 and 2000.) I'm familiar with using Expect to return data from...
