EndeavourOS do ship only default .bashrc (bash configuration) but as you may know there are endless.

Here you will find some basic settings and hints on customizing your bash prompt and behavior of the shell.
~/.bashrc Per-user config file, applied after /etc/bash.bashrc
~/.bash_profile Per-user, after /etc/profile. If this file does not exist, ~/.bash_login and ~/.profile are checked in that order. The skeleton file /etc/skel/.bash_profile also sources ~/.bashrc.
~/.bash_logout Per-user, after exit of a login shell.
/etc/profile Sources application settings in /etc/profile.d/*.sh and /etc/bash.bashrc.
Most requested is the history search function added on top of up/down keys showing the history roll of input:
Add these two lines to users .bashrc:
bind '"\e[A":history-search-backward' # history with arrow up key
bind '"\e[B":history-search-forward' # history with arrow down key
With this you can start typing per example sudo and with up and down keys it will show all commands used starting with sudo…
The prompt itself can be configured and as you like in many many ways also for some examples see this online tool per example:
