[BASH] Ctrl-U Ctrl-Y command line trick
=========================================
**Use case:**
You’re typing a command, for example you're typing: `[sudo] apt-get upgrade`,
but suddenly realize you should execute `[sudo] apt-get update`
first.
**Solution:**
Go at the end of your current command with `Ctrl-E`, then press `Ctrl-U`,
type and execute the other command, then press `Ctrl-Y`.
***Tadaa!***
