Send One Line From a Text File as as SMS Every 10 Mins

Tagged with: , , , ,

This command will send a line from a given text file one every 10 mins as an SMS to a given number.


i=1; while [ 1 ]; do sms INSERT_PHONE_NUMBER "$(cat "/home/binnyva/sms.txt"|head -n$i|tail -n1)"; sleep 10m; i=$(expr $i + 1); done

Script calls the command ‘sms’ – you can define that command however you want. In my case, its a variation of this script.
