A shell script for Tot

tot.sh

#!/bin/bash

# Fork of CHOCK's original tot.sh to add support for dot "0" to target
# the first empty dot.
# https://gist.github.com/chockenberry/d33ef5b6e6da4a3e4aa9b07b093d3c23
#
# 2 Mar 2020
# + Incorporated suggestions from ShellCheck (https://www.shellcheck.net).
#   Thanks to Ramsey Dow.
# + Changed call to `python` to `/usr/bin/python` to get Python 2, avoiding
#   conflicts for folks whose default `python` is Python 3.
