logs get mixed when using `expect_string` inside `send_command()`

Hi! I’m trying out the new version of netmiko 4.1.0. I’m upgrading a set of tools that I was using with netmiko 3.4.0. I’m using device type nokia_sros with a range of timos versions (7.x, 9.x, 16.x, 21.x).

When using send_command() with show-like commands, I used to store the received outputs both in a json file and a plain text file.

These are a snippet of the commands I’m sending to the router:

# SCRIPT_NONO_START
/environment no more
/show router bgp summary
/show router interface
/show service sdp
/show service sdp detail

This is how I store the recevied output:

try:
    for cmd in cmdList:
        rx        = conn2rtr.send_command(cmd, expect_string=r"#", cmd_verify=True, read_timeout=10)
        outputTxt = outputTxt + '\n' + cmd + '\n' + rx
        outputJson[cmd] = rx
    outputReason = ""
    runStatus    = 1
except Exception as e:
    outputTxt    = ''
    outputReason = str(e)
    runStatus    = -1

But here is a problem. If I enable the expect_string inside the send_command(), then my ouput both in the json or the text file, gets scrambled. The output on the left corresponds to the case where exptect_string is enabled; on the right, I’m not using it. You can see on the left how the sent commands are being repeated, like echoed.

This is a snippet of the json file. Look how the values for each key, are mixed.

I was using the expect_string before, to speed up things, but the output gets corrupted.

However, everything seems to be allright if I do not use the expect_string.

Any hint?

thanks!

Yes, that was it … thank you …

Have you tried:

r"#\s+$"

In other words, are you sure there is no whitespace between the # and the end-of-line?
