Betty is an open source tool that translates English-like phrases into Linux commands. The main goal of this project is to use the Linux powered systems through natural language input. Let us see some examples how it works.

Installation

Betty installation is very simple and straight forward. Make sure you’ve installed the following prerequisites packages.

On Debian based systems:

sudo apt-get install git curl ruby

On RPM based systems:

yum install git curl ruby

Now, git clone the Betty repository to any preferred location. I am going to clone the betty repo in my home directory i.e /home/sk/.

git clone https://github.com/pickhardt/betty

Add the betty alias in your bashrc file.

sudo nano ~/.bashrc

Add the following line at the end:

alias betty="/home/sk/betty/main.rb"

Make sure you’ve replaced the correct path of the betty directory.

It’s done. Now, it’s time to play with betty.

Usage

You should include the word “betty” in-front of every English phrases. As you may know already, if we want to know the user name of our system, we run the following command:

whoami

Sample output:

sk

As you see above, my current user name is sk. Well, now we can get the same result using betty as shown below.

betty whats my username

Sample output:

Betty: Running whoami
sk

Cool, isn’t it? Yes. Betty understands the normal English phrase “whats my username” that I entered, and ran the command “whoami” automatically, and finally displayed the correct output.

Let us see some other commands too.

Betty will respond in multiple ways if you didn’t enter exactly what you’re looking for. For example, we run the following command:

betty whats my name

Betty isn’t sure whether she should find the system username or full name. In this case, she will ask you multiple questions to find the exact result. As you see below, Betty asks me which command(whoami or  finger $(whoami) | sed ‘s/.*: *//;q’) should I want to execute. I just want it to display my username, so i chose number 1.

Betty: Okay, I have multiple ways to respond.
Betty: Enter the number of the command you want me to run, or N (no) if you don't want me to run any.
[1] whoami
Gets your system username.
[2] finger $(whoami) | sed 's/.*: *//;q'
Gets your full name.
1
Betty: Running whoami
sk

Compress And Uncompress Folders

If you want to compress a file or a folder, use the following command. For example, I want to compress a folder called “test” folder in my home directory.

betty compress test/ test.tar.gz

Sample output:

Betty: Running tar -czvf test.tar.gz test/
test/
test/home/
test/home/sk/
test/home/sk/test/
test/home/sk/test/sample

Similarly, we can use the following command to uncompress an archive file.

betty uncompress test.tar.gz

Sample output:

Betty: Running mkdir test &&  tar -zxvf test.tar.gz -C test
test/
test/home/
test/home/sk/
test/home/sk/test/
test/home/sk/test/sample
