What are the differences between temporary and permanent environment variables?

Temporary environment variables are set for the duration of a session, while permanent ones are saved across sessions.

Can you give me an example of how to set a temporary environment variable?

Sure! In a Unix-like system, you can set a temporary variable using export VAR_NAME=value in the terminal.

How do I make an environment variable permanent?

To make it permanent, you can add the export command to your shell's configuration file, like .bashrc or .bash_profile.

Are there any risks associated with permanent environment variables?

Yes, if not managed properly, they can lead to conflicts or security issues, especially if sensitive data is stored.
