itunec

#!/usr/bin/python3

#  Decription
#  -----------
#  Mounts USB device, syncs new podcast in gpodder then umounts device

#  Author: [Dmitry](http://dmi3.net) [Source](https://github.com/dmi3/bin)

#  Requirements
#  ------------
#  1. `sudo apt-get install python3 id3v2`
#  2. `wget https://raw.github.com/dmi3/bin/master/notify-append -P ~/bin && chmod +x ~/bin/notify-append`

#  Usage
#  -----
#  1. set LABEL to label of your player filesystem (for example `SANSA CLIP` to find label type `ls -l /dev/disk/by-label/`)
#  2. set GPODDER_DIR to directory where gpodder download podcasts
#  3. run `itunec` when you want to sync
#  or
#  1. gpodder -> Podcasts -> Prefences -> Devices; set  Device type to `Filesystem-based` and `Mountpoint` path where device is mounted by default
#  2. gpodder -> Podcasts -> Prefences -> Edit config -> cmd_all_download_complete -> itunec
