In this post, we are going to develop a simple alarm with shell scripts.
To get the time we use date command. To play a sound file we use aplay command-line player. It is also a recorder. Since we are developing an alarm it must control the time continuously so we need an infinite loop. Source codes are given in the following.
Source Codes:
By changing the controlled time and sample.wav you can adjust it as you want.

while :
do
echo "Press [CTRL+C] to stop.."
now=$(date +"%H:%M")
echo "Current time : $now"
echo " is current time true ?"
if [ "$now" == "08:06" ]; then
echo "Yes!"
aplay sample.wav
else
echo "No!"
