How to Make Your Cisco Router CLI UNIX Command Friendly!

When Ken Thompson, Dennis Ritchie, and Joseph Ossanna started their work on the UNIX operating system way back in 1970 at Bell Labs I bet they never imagined that you would be able to run a number of the common UNIX utilities like ‘grep’ or ‘uname’ on a Cisco router running the Internetwork Operating System (IOS)!
In this video tutorial we take a deep dive look at just how you can turn your Cisco router’s IOS command line into a pseudo UNIX-like environment where you can create functions, leverage UNIX utilities and create full blown functions! We also compare and contrast the use of IOS aliases and when using a UNIX function might be a good choice. Enjoy!
