 1 | ## Alarm Clock
 2 | 
 3 | #### Sankha Narayan Guria ([sankha93@gmail.com](mailto:sankha93@gmail.com))
 4 | 
 5 | This is just a simple shell script that acts as an alarm clock. A natural consequence of my habit of sleeping on the laptop! So nothing seemed better than turning my laptop into an alarm clock to wake me up. Currently this works on a Linux system and needs `mplayer` to be installed.
 6 | 
 7 | #### To Use
 8 | Download all the scripts and run the following in a terminal:
 9 | 
10 | `./alarm.sh`
11 | 
12 | In the `buzzer.sh` file change the `file` variable. To change the snooze time change the `snooze` variable in the file `alarm.sh`.
