Setting up a proper environment is very important for running a process. An environment consists of environment variables that may or may not have a default value set. The required environment is set by modifying the existing environment variables or creating new environment variables. Environment variables are exported variables that are available to the current process and also its child processes. In Chapter 1, The Beginning of the Scripting Journey, we learned about some of the builtin shell variables that can be used in our application as environment variables to set the environment.
