如果感到无聊，可以在 Debian 系统里面开水族馆养鱼

sudo apt update && sudo apt install perl libcurses-perl make wget -y && \
sudo cpan Term::Animation || (cd /root/.cpan/build/Term-Animation-2.6-* && sudo make install) && \
cd ~ && wget https://www.robobunny.com/projects/asciiquarium/asciiquarium.tar.gz && \
tar -zxvf asciiquarium.tar.gz && \
cd asciiquarium_1.1/ && \
sudo cp asciiquarium /usr/local/bin/ && \
sudo chmod +x /usr/local/bin/asciiquarium && \
asciiquarium

运行这一段代码，就可以开水族馆了
