Building on the previous post where the requirement was to have cron jobs send status messages via a single command line, as posted here:
The question came up as to how to use a single line to send an attachment file.
cron job generates the output file like so:
cd /home/pi/python gnuplot plt12
the program file plt12 includes the following two lines:
set output "pl12.png" set terminal png font "arial,11"
This is being done on a Rpi3B system connected via USB to a Nano for the ADC which does the data logging.
So, the question is, what is the easiest way to send that plot file image, using a single command line, via gmail?
