Generate QR codes in your terminal.

I found it very useful to generate QR code for my gridcoin wallet staking on my raspberry pi to send some money there from my mobile wallet.
I didn't wanted to manually type the address to avoid mistakes and I was too lazy to copy it via ssh or send it via email to myself.
I just wondering if it might be helpful to anyone so I decided to share it.
Solution turned to be very easy. Easy as the following few lines:

• Login to your raspberry PI
• Install qrencoder:

$ sudo apt-get update && sudo apt-get install qrencode -y

• Get your address. I use gridcoin wallet, but it is valid for almost any headless daemon. As most of them just bitcoin forks the terminal command are very similar.
  For gridcoins you can use

$ gridcoinresearchd listaddressgroupings

Or request transactions list and get it from here

$ gridcoinresearchd listtransactions

• Generate QR code:

$ qrencode -t UTF8 YOUR_ADDRESS_IS_HERE

As a result you will get very nice and neat QR code which will be possible to scan and use (as at the screenshot above).

Good luck!
