simple alarm clock with bash scripting

In tips & tricks on 14 January 2008 tagged alarm clock, bash programming, linux with 7 comments

here is a simple bash programming that will execute alarm when it reach certain time setup by user

initially i coded just for exercise on bash scripting (practice make perfect right?) but i think it's a good idea to share it with other people

here's the code
#!/bin/bash
masa="`date +%k:%M`" mp3="$HOME/Desktop/alarm.mp3" #change this
if [ $# != 1 ]; then echo "please insert alarm time [24hours format]" echo "example ./alarm 13:00 [will ring alarm at 1:00pm]" exit; fi alarm=$1 if [[ "$alarm" =~ ^[0-2][0-9]\:[0-5][0-9]$ ]] #fix me with better regex >_< then echo "time now $masa" echo "alarm set to $alarm" echo "will play $mp3" else echo "invalid clock format" exit; fi
while [ $masa != $alarm ];do masa="`date +%k:%M`" #update time done echo $masa if [ $masa = $alarm ];then echo ringggggggg play $mp3 > /dev/null 2> /dev/null & fi exit
if you have any suggestion/comment to improve this code please tell me

thanks

note : you will need sox to use "play" command, debian/ubuntu user can install it by sudo apt-get install sox
