I am installing Ros2 on my Ubuntu PC and want to make sure the installation steps won't affect my PC, in particular I need to know what this command actually do:
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/nullThanks for breaking it down for me.
