NEXOS Sort command key

[Zeroedin]

Hello,  I have a switch with nxos.9.3.1 and I am trying to sort the "show mac address-table" output by the interface. I have the command "show mac address-table | i Eth | sort -k" so far and wanted to know how I could use the -k as I was not able to find any documentation about it. Do I have to convert it to JSON first? Is there some specific documentation that could help me with this issue?

This is an example output:

* 3000 aaaa.aaaa.aaaa dynamic 0 F F Eth1/1

Thank you

-k field-number[.char-position][ordering]

Sorts according to a key value. There is no default key value.

I was not sure what is the outcome you expecting :

here is document for sort usage.

I saw this exact documentation but I don't understand too well. What is "field-number" and [.char-position][ordering] in relation to what I needed to be sorted. The documentation doesn't explain too well.

Post the full output of your show command / what you want to sort with -K ?

the example show output you posted on original post not help since its single value.

 Could I use -k to sort by interface? I am not really sure how it works.

[balaji.bandi]

not that you can do that with sort in the box - may be get the information out of the box and process using Python is best option, you can look below example :

What you need exactly?

You want to know meaning of -K
