By default, Alpine Linux uses the Ash shell, which is a lightweight and efficient shell. However, if you prefer to use the Bash shell, you can install it by running the following command:
apk add bash
This will download and install the Bash shell package from the Alpine Linux package repository.
After installation, you can start a Bash shell by running the following command:
bash
To make Bash the default shell for your user, you can run the following command:
chsh -s /bin/bash
You will be prompted for your password, and the default shell for your user will be changed to Bash the next time you log in.
