How to remove new line from Terminal on launch?
Comment out or remove the following three lines from ~/.zshrc
#echo -e &quot;\033]6;1;bg;red;brightness;18\a&quot;
#echo -e &quot;\033]6;1;bg;green;brightness;26\a&quot;
#echo -e &quot;\033]6;1;bg;blue;brightness;33\a&quot;

Each echo actually creates a new line (on BigSur 11.2.3) and together they create 3 new lines on every new window/tab.
