Run command after open OS Manjaro

[mman]

How can I execute a command or file.sh on the terminal using Bash language after opening my computer without any intervention from me?

example :

$ echo 'hello' > ~/Desktop/start.txt

Easy:

mkdir -pv ~/.config/plasma-workspace/env/
echo "echo 'hello' > ~/Desktop/start.txt" > ~/.config/plasma-workspace/env/start.sh
