Ever wanted to check an URL periodically, and print out a copy if it's changed?
$ go install github.com/adammck/autoprint@latest
$ autoprint -h
usage: ./autoprint [options] <url>
options:
-f ignore etag to force download
-n don't print anything
-v enable verbose logging
For example:
$ autoprint https://pdfobject.com/pdf/sample.pdf
Printing...
$ !!

Use cron or launchd or systemd or whatever to run it periodically.
