Betty is not doing any complex task and can perform some basic things. I’m going to run few commands to test this.

$ betty what is my username
Betty: Running whoami
daygeek

$ betty what is the date
Betty: Running date +"%a %d %b, %Y"
Fri 22 Feb, 2019

$ betty what is my kernel
Betty: Running uname -a
Linux daygeek-Y700 4.19.20-1-MANJARO #1 SMP PREEMPT Wed Feb 6 21:33:34 UTC 2019 x86_64 GNU/Linux

Betty will show the following statement if it is not understanding your query.

$ betty update the system
Betty: I don't understand. Hopefully someone will make a pull request so that one day I will understand.
