Learn BASH with me in 5 mins

I just started learning Linux bash from today. From my first impression of the language, I infer that it is a language with all the basic capabilities as of an infant high level language. May be I am right or wrong.Time will tell . We will keep going and keep discovering gradually. Let's start with the usual protocol of learning a language.

The HELLO WORLD program.
How to print things in shell. This is the first thing everyone wants to know while learning any language.

Anything that is not a variable is printable . And we print/echo it using the famous ECHO keyword

$ echo hello world hello world
Printing a number.
$ echo 1 1 Printing a string with double quotes$ echo"my name is arindam" my name is arindam Printing a string with single quotes$ echo'my name is Arindam' my name is Arindam Printing a number with quotes$ echo'1' 1
Creating  Variables and recalling them.
So how can we store things. How to recall that stored value. How to change that value.
