Variables in windows command prompt

There are 2 types of variables.
  • User defined
  • Environment variables

Creating user defined variables

We can create new variables using set command.
set <variable-name>=<value>

set browser=chrome

To display the value of variable, you can use below command.
echo %<variable-name>%

For example – to view the variable “browser”, you can use below syntax.
echo %browser%
