   echo $SHELL
   

   This command will display the path to the current shell executable.

Step 2: Install New Shell (Optional)

If you want to switch to a different shell that is not already installed on your system, you can install it using the package manager. For example, to install Zsh, you can use the following command:

sudo apt install zsh

Step 3: Change Default Shell

1. Once you have installed the desired shell, run the following command to change the default shell for your user account:

   chsh -s /path/to/new/shell
   

   Replace /path/to/new/shell with the path to the executable of the new shell (e.g., /bin/zsh for Zsh).

2. You may need to enter your password to confirm the change.

3. Close the terminal window and open a new one to apply the changes.

Step 4: Configure Shell Preferences (Optional)

1. After switching to the new shell, you can customize its behavior and appearance by editing configuration files.

2. For example, for Zsh, you can edit the ~/.zshrc file to configure settings such as prompt, aliases, and plugins.

3. Refer to the documentation or community resources for your chosen shell for more information on customization options.

Step 5: Verify Shell Change

1. Open a new terminal window.
2. Run the echo $SHELL command again to verify that the new shell is now the default.
