I was so happy when I discovered this. As a UNIX and Linux user for my entire career I was so surprised that something built into every Cisco, Juniper, Arista etc etc network device wasn't built into many cli tools on Linux.

I know I can create aliases and whatnot, but I'm a consultant, when I was still hands on with the tools I'd log into 30+ different customer's environments every year. Many were isolated from the Internet and whilst I did carry my dotfiles around on a USB (Along with some binaries of useful tools that are so often lacking on enterprise systems) I couldn't always use them.
