QR code: show in Linux

Well, in case you ever wanted to quickly (3 sec) pass a string to your phone, here is how:

1. run the script qr-show.sh I list below
2. feed the string to it
3. scan the QR code with the Barcode Scanner with your phone (get from F-Droid or Play Store)
4. easy!

The script:

 #!/bin/bash -e

TEXT=`yad --entry --entry-label='Enter string to encode'`

qrencode -o $TMP/qr.png "$TEXT" &&
        eog -ng $TMP/qr.png &

You can see a few tools used which of course can be replaced by alternatives:

1. yad with zenity/gdialog/xdialog/dialog
2. eog with geeqie/any other image viewing
3. Barcode Scanner with any barcode scanner ))
