Introduction

Why should we learn Linux?

NOS Linux shells - Cisco, Arista, Cumulus Linux

NOS (Network Operating Systems) mostly run on Linux such as Cisco Routers, Arista and Cumulus Switches etc

Packet Pushes have a nice reference to NOS systems which a lot are all built on Linux and other Open Source hardware (Facebook Opensource Switches for example) Pica8, Cumulus Networks, Microsoft Sonic (go figure!! :)

You can't run Ansible Control Machine on Windows. Only on Linux or docker container.

Cisco IOS Linux commands

Working with the Cisco IOS file system, config files and software images, this all required knowledge of Linux and the command line.
