I am writing this bash script, that will read a file containing a date, a time and a phone number, and it will use an SMS provider API to send an sms reminder.

#!/bin/bash



while read date time phone

do



user=user

pass=pass

senderid=senderid

message=Your%20appointment%20is%20at%20$date%20$time.%20For%20cancellations%20call%2096989898.%20Thank%20you.

api="https://sms.service.com/Websms/sendsms.aspx?User=$user&passwd=$pass&mobilenumber=357$phone&message=$message&senderid=$senderid&type=0"



curl -k $api



done < ~/sms_reminders/events/events_$(date +%d-%m-%y)

When I run it like this, I receive an SMS immediately. But I want to schedule the reminder to go out at a specific time. So I change the script to this.

#!/bin/bash



while read date time phone

do



user=user

pass=pass

senderid=senderid

message=Your%20appointment%20is%20at%20$date%20$time.%20For%20cancellations%20call%2096989898.%20Thank%20you.

api="https://sms.service.com/Websms/sendsms.aspx?User=$user&passwd=$pass&mobilenumber=357$phone&message=$message&senderid=$senderid&type=0"



echo curl -k $api | at $time



done < ~/sms_reminders/events/events_$(date +%d-%m-%y)

And I get a message saying

warning: commands will be executed using /bin/sh

job 22 at Fri Jun  6 21:46:00 2019

Which is good.

But I never receive the SMS.

My guess is that the issue has something to do with sh, but I have no way of being sure because at doesn't really generate a log file saying if the command was completed successfully or not.

  Is the date and time correct in the output of the at command? The date and time that you show has not occurred anywhere on the planet yet.

  Have a look at whatever log file cron writes to and see if atrun or similar process executes your scheduled jobs. I'm assuming that atq does not show the jobs any longer?
