#!/bin/bash
echo -e '\e[31m'    # escape character for red font
s=6
for i in `seq 8 2 16`; do
    if [ $i -ne 10 ]; then
        for j in `seq $s`; do
            echo -n ' '
        done
        for j in `seq $i`; do
            echo -n '#'
        done
        echo
    fi
    s=`expr $s - 1`
done
echo -e -n '\e[97m'    # escape character for white font
s=2
for i in `seq 16 -2 8`; do
    if [ $i -ne 10 ]; then
        for j in `seq $s`; do
            echo -n ' '
        done
        for j in `seq $i`; do
            echo -n '#'
        done
        echo
    fi
    s=`expr $s + 1`
done
echo -e '\e[0m'    # escape character for default font color
