Variables work as temporary storage for any programming language. The coder needs to have a clear concept of using different variables in the code. Variables are used to store specific data. The most commonly used data type of variables are integer, string, float, double and Boolean. The data type of any variable has to be defined at the time of variable declaration for strongly type programming languages. But BASH is a weakly typed programming language that does not require to define any data type at the time of variable declaration. So when any numeric value assigns to a variable then it will work as integer and when any text value assigns to a variable then it is string. BASH variables can be used from terminal or on any BASH file. The use of different types of BASH variables are described in this tutorial by using many examples. Read More
