How can I clean the terminal?

[Aegon]

I want to clean the terminal when it opens. I like the theme but I don't like the details it shows every time I open the terminal.

Remove fastfetch /neofetch / paleofetch from .bashrc / .zshrc / fish.config

I never used Garuda GNOME

The ascii-art and the text are the output of a program, fx. could be neofetch, paleofetch or fastfetch like @SGS said. This program runs by default because it is called in the config file, ie .bashrc or .zshrc for your shell.

I found fish.config file in home/.config/fish.confg
And I removed the keyword neofetch in the lastline.
And it worked. I found neofetch folder in .config and I also deleted that.
Is it fine?
