Avoiding similar commands in Konsole when scrolling through recent commands in Manjaro KDE

Question

Imagine that I enter these commands in Konsole (Manjaro KDE terminal):

python3 script.py
clear
clear

Normally when I hit arrow UP key, I am able to scroll through recent commands: If I hit arrow UP key three times I should have these commands

clear
clear
python3 script.py

Is there a way to avoid having similar commands when hitting arrow UP key?
What I want here is to have

clear
python3 script.py

FYI, this is a function of your shell (bash), not a function of the terminal (konsole). — Stewart, Nov 29 '20 at 16:19
If you are using bash (in the terminal), then yes. Look up history. There is an option to remove adjacent duplicates. — ctrl-alt-delor, Nov 29 '20 at 17:30
Does this answer your question? How can I remove duplicates in my .bash_history, preserving order? The first answer is to clean the existing history file, the second to configure history to ignore duplicates. — thanasisp, Nov 29 '20 at 17:46

Add the following to your ~/.bashrc if you're using bash:

export HISTCONTROL=ignoreboth:erasedups

If you're using zsh, you can try this in your ~/.zshrc(untested):

setopt HIST_IGNORE_DUPS
