Customize BASH shell

1. Switch to root user

I usually create it under root and then replicate to any other users on the system. It’s a matter of preference.

sudo su
cd

2. Back up the original files

mv /root/.bashrc /root/.bashrc_bak
mv /root/.inputrc /root/.inputrc_bak
mv /root/.bash_aliases /root/.bash_aliases_bak

Repeat the same for any other user.

3. Download config files
