A simpler way to send pushover notifications using bash
Every argument for pushover available directly from the terminal, supports configuration files.

./bashover.sh -t "token-goes-here" -u "user-key-here" -m "Hello World" --title "Bashover"

./bashover.sh -t "token" -u "user" -m "Here is the latest screenshot" --title "Screenshot" --attachment ~/screenshot.png --priority "1" --sound "tugboat" -v

./bashover.sh -c ~/.conf/bashover/server.conf --attachment ~/temperatures.png -m "High temperature on drive 1" --title "Warning: high temp"

The script creates a defaul config.file at ~/.config/bashover/default.conf where default values for all arguments can be stored.
Parsed arguments takes precedence, and default values can be ignored by parsing -i or --ignore-defaults.

This way token, user key and title can be stored as defaults, and a message can be sent by a simple command as ./bashover.sh -m "Hello World"

Additional config files can be used, and parsed using the -c or --config argument.
./bashover.sh -c ~/my-bashover-config.conf
