What Others Think

Hmm... The first while loop looks a bit strange. I didn't know you could have multiple commands in the while condition. That said, you don't need the "true;", "while sleep 1;" is OK. The command's clever but the output is terrifying :-)

Can be done less frightening easily ;-) clear;while true; sleep 1;do for ((a=1; a <= $(tput cols)/3; a++)); do tput cup 0 $a;echo " " "tempus fugit, memento mori";done;sleep 1;for ((a=a; a>=1; a--)); do tput cup 0 $a;echo $(date) " ";done; done

Or ... let's rather be more optimistic :-) clear;while true;sleep 1;do for((a=1;a<=$(tput cols)/3;a++));do tput cup 0 $a;echo " " $(date);done;sleep 1;for((a;a>=1;a--));do tput cup 0 $a;echo "$((($(date -d "2015-12-12" +"%s")-$(date +"%s"))/86400+13)) days till next Christmas" " ";done;done
