Episode #173: Tis the Season

Hal finds some cheer
From somewhere near the borders of scriptistan, we send you:

function t { 
    for ((i=0; $i < $1; i++)); do
        s=$((8-$i)); e=$((8+$i));
        for ((j=0; j <= $e; j++)); do [ $j -ge $s ] && echo -n '^' || echo -n ' '; done;
        echo;
    done
}
function T {
    for ((i=0; $i < $1; i++)); do
        for ((j=0; j < 10; j++)); do [ $j -ge 7 ] && echo -n '|' || echo -n ' '; done;
        echo;
    done
    echo
}
t 3; t 5; t 7; T 2; echo -e "Season's Greetings\n    from CLKF"

Ed comes in out of the cold:

Gosh, I missed you guys.  It's nice to be home with my CLKF family for the holidays.  I brought you a present:

c:\>cmd.exe /v:on /c "echo. & echo A Christmas present for you: & color 24 & 
echo. & echo     0x0& for /L %a in (1,1,11) do @(for /L %b in (1,1,10) do @ set /a
%b%2) & echo 1"& echo. & echo Merry Christmas!

Tim awaits the new year:

Happy New Year from within the borders of Scriptistan!
