This is HPR episode 2,379 entitled, sending a text message from the command line.
|
|
It is hosted by Genre and is about 5 minutes long, and carries an explicit flag.
|
|
The summary is a bunch of waffling on about email and text message sending from the command line.

Hello HPR listeners, my name is Jezra, and I'm going to talk about sending a text message
|
|
from the command line on a GNU Linux computer.
|
|
This episode is being recorded on a GNU Linux laptop with a Logitech USB headset and audacity
|
|
as the recording and editing software.
|
|
The need to be able to send myself a text message came about when I was building my GNU Linux
|
|
powered chicken coop door.
|
|
If there was a problem opening or closing the door, I wanted the controlling computer to
|
|
be able to send me both an email and a text message.
|
|
The computer controlling the chicken coop door is a beagle bone black running devian.
|
|
In order to send an email from the command line, I first needed to install the mail ex command
|
|
line email client.
|
|
In order to accomplish this, I installed the heirloom mail ex package from the devian repositories.
|
|
Once the necessary software was installed, I signed into my domain registrar and created
|
|
a new email account specifically for my shed.
|
|
The computer that controls the chicken coop door is in my shed, and I wanted all emails
|
|
coming from the shed to be sent from shed at Jezra.net.
|
|
So a new email account with name and password was created.
|
|
The next step in the process involved reading the mail ex documentation and crafting a command
|
|
line script to allow mail ex to connect to SMTP at my email host and send an email from
|
|
shed at Jezra.net to Jezra at Jezra.net.
|
|
The script was later modified to allow for a sentence to be sent as a command line argument
|
|
and that sentence will then be the body of the email that gets sent to me.
|
|
The script was given the descriptive but very boring name of email Jezra.
|
|
From the command line, I would type email Jezra problem closing the door or email Jezra
|
|
problem opening the door and then I would get sent an email with the body that says problem
|
|
opening the door or problem closing the door, you get the idea.
|
|
Sending a text message instead of an email is an extremely similar process.
|
|
The email Jezra script was copied and renamed as text Jezra.
|
|
Most mobile phone service providers offer an email address that is based on one's telephone
|
|
number and when an email is sent to that email address it will result in a text message
|
|
being sent to that phone number.
|
|
Basically the address is phone number at some special domain based on the provider.com.
|
|
In my case, I use an MVNO that piggybacks on the Verizon network.
|
|
So I modified the text Jezra script to not send the email to Jezra at Jezra.net but
|
|
to send the email to my phone number at the special domain.
|
|
Thus, when I type in text Jezra, hello, how are you doing?
|
|
The end result will be a text message coming to my phone from Shed at Jezra.net saying
|
|
hello, how's it going?
|
|
And that my friends is a fairly easy way to send a text message from the command line on
|
|
a GNU Linux computer.
|
|
Aside from notifying myself when the chicken coop door has problems opening and closing,
|
|
every day at 8 a.m., I run a crontask that scrapes the website of the local air quality
|
|
board and sends me a text message letting me know what the air quality is going to be
|
|
like that day.
|
|
And I would like to know what you, the HPR listener, would send to themselves as a notification
|
|
and how it would be done.
|
|
So fire up your mic, record an episode, and let me know.
|
|
Thank you and have a wonderful day.
