- Open a Terminal: Whether you’re using GNOME Terminal, Konsole, or any other terminal emulator, open it to get started.
- Check Your Current Shell: Before switching, it’s a good idea to check which shell you’re currently using. You can do this by typing
echo $SHELLand hitting Enter. This command will display your current shell.

bashand hit Enter. You’ll be instantly switched to the Bash shell, and your prompt will change accordingly.

Navigating the File System
One of the fundamental tasks in any shell is navigating your file system. In Bash, you can use commands like
cd to change directories and
ls to list the contents of a directory.
Bash allows you to run a wide range of commands, from simple ones like
ls to more complex ones like compiling code or managing packages. You can even chain commands together using pipes (
|) for more powerful operations.
Bash supports variables, which allow you to store and manipulate data. You can create variables and use them in your scripts to make them more dynamic and flexible.
Scripting in Bash
For those looking to automate tasks or write custom scripts, Bash is an excellent choice. You can create scripts to perform repetitive tasks, schedule them, and even share them with the Linux community.
Advanced Bash Techniques
Bash keeps a history of your commands, making it easy to recall and reuse previous commands. Use the
history command to see your command history.
Customizing Your Bash Prompt
Personalize your Bash experience by customizing your prompt. You can display useful information, such as your username, hostname, and current directory, right in your prompt.
Aliases allow you to create shortcuts for frequently used commands. They can save you time and typing effort. Define your aliases in the
.bash_aliases file in your home directory.
Can I switch back to my previous shell after using Bash?
Yes, you can switch back to your previous shell by simply typing its name (e.g.,
fish) and pressing Enter.
Is Bash the same on all Linux distributions?

Can I use Bash on macOS?
