A single-file Python script to send Pushover notifications via the command line.
A standard installation of python3 should be all that is needed.
Two lines in pushover.py will need to be changed in order to use it: the APP_TOKEN value and the USER_KEY value.
To obtain a user key, log in or sign up for Pushover at https://pushover.net. Once logged in, "Your User Key" should be present on the right hand side. Replace USER_KEY_HERE with the user key shown.
Next go to "Apps & Plugins" on the Pushover site and click "Create New Application". Enter a name, description, and optional URL, and select "Script" as the type. Once the application is created there should be a "API Token/Key" shown. Replace APP_TOKEN_HERE with the token shown.
Once these two changes have been made the script should be ready for use.
