Shell Script Creating a Talking Alarm Clock on Ubuntu

A Beginners Shell Scripting tutorial

This tutorial was an idea to put a talking alarm clock together using shell script in Ubuntu. It plays mp3, Uses festival as a text to speech engine. It reads time correctly, and weather based off of weather station near you. It pulls weather info via weather-util from http://weather.noaa.gov/ and then just choose your location for ID. Also Gradually increases volume. Uses two files alarm1 in home directory, and wakeup-volume in /usr/local/bin

I developed this as a fun project that would help anyone to learn some simple shell scripting.

code for Alarm #
#!/bin/bash

sleep 3

PLAYER=/usr/bin/mplayer
SONG="$HOME/alarms/alarm.mp3"
killall wakeup-volume
/usr/local/bin/wakeup-volume&
$PLAYER -loop 1 "$SONG"
sleep 5
echo "Good Morning, I hope you slept good and I hope you have a great day" | festival --tts

echo "The time is $HR $MIN" | festival --tts

# Set up a variable to hold the current minute
# of the hour using the date command:
MIN=$(date +"%M")

# And another to hold the current Hour:
HR=$(date +"%l")

# Use a case statement to change the minute
# number to the equivalent word, but make the
# zero minute "o'clock". Handle all sixty minutes
# of the hour so this works correctly for any time.
