What is the primary use of the command 'env' in Shell Scripting?

The command 'env' in Shell Scripting is primarily used to run a command in a modified environment. It allows users to dynamically alter the environment variables before executing a specified command, which can be beneficial in various situations. For instance, if you need to run a program with specific environment variables that differ from the current shell environment, 'env' provides a straightforward way to accomplish this.

When you invoke 'env' followed by the desired command, it sets the environment for that command alone, ensuring that any changes to the environment variables do not affect the shell session that invoked it. This feature is particularly useful for testing, debugging, or executing scripts that require a specific set of environment variables without permanently changing the environment of the terminal session.

While creating a new environment variable, displaying the current directory, or compiling a script are tasks associated with other commands or methods, their functionalities do not align with the primary purpose of 'env', making it a specialized tool for environment management.
