I'm new to Ubuntu and I'm going through the official documentation. Can someone explain why the command sudo apt-get install -y boot-repair && boot-repair lists "boot-repair" twice?

The last line contains two commands.
The first part installs boot-repair. (sudo apt-get install -y boot-repair)
The "&&" characters is a delimiter like ";" is, however its conditional on success, ie. the command following it is only to be run IF the first command had no errors.
The 'second' boot-repair is the one that runs it.

If you used a ";" and the install command worked; the result would be the same as it'd install, then run. If however the install failed you'd get errors for the install failing, followed by more errors asboot-repaircouldn't be found... The && conditional parameters reduces the errors (if they occur) as they [errors] can scare users (what did i do wrong? did i break it?..)

oh of course, that makes sense. Thank you. I was thinking that it was trying to install it twice.
