What Is the Linux Terminal?
The terminal (also called the command line, console, or shell) is a text-based interface where you type commands to control your Linux system.
Most Linux systems use Bash (Bourne Again SHell) as the default shell, but others exist too (like Zsh, Fish, etc.).
How to Open the Terminal
Depending on your Linux distro or desktop environment, you can open the terminal in one of these ways:
| Desktop Environment | How to Open Terminal |
|---|---|
| Ubuntu (GNOME) | Press Ctrl + Alt + T or search “Terminal” in the menu |
| Linux Mint (Cinnamon) | Ctrl + Alt + T or search for Terminal |
| KDE Plasma | Alt + Space then type “Konsole” |
| XFCE | Menu > Accessories > Terminal Emulator |

/home | User folders |
/etc | System configuration files |
/bin | Essential system binaries |
/var | Variable data (logs, spool files) |
