Set Ubuntu shell for Xilinx PetaLinux

Hi !

In this post we are going to set the default shell used by Ubuntu.

In our case we will use the bash shell because Xilinx PetaLinux tool requires it !

Stage 1

First, let's find what is the current type of shell set in our Ubuntu installation.

Use the following command :

ls -l /bin/sh

Ok, actual shell is dash.

Stage 2

So we need to switch to bash.

Use the following command :

sudo dpkg-reconfigure dash


This will bring the following screen to pop up in the terminal.

Change the selection to NO using the key, then press Enter.

The log tells you that the dash shell is removed and replaced by the bash shell.

Stage 3

Now, if you check again the current shell then you get the bash one this time.

Post Conclusion

Now we have :

- Set Ubuntu's default shell to BASH.
