Your Shell's Environment
Welcome! In this lesson, we'll dive into how your Linux shell keeps track of important information. This 'environment' helps your commands run smoothly.
Think of it as your shell's personal workspace, full of settings and shortcuts.
Meet Environment Variables
Environment variables are dynamic named values that store information used by the shell and other programs. They let you customize how your system behaves.
- They are like temporary storage for your shell.
- They can hold paths, user settings, and more.
- Other programs can read these variables to know how to act.
