rsync the files of an itunes playlist with another directory, most likely a usb
2
-
music device.
1
+
A couple scripts for maintaining a directory of music files (probably located
2
+
on a USB music player or SD card) from an iTunes playlist.
3
+
4
+
Requires the `appscript` gem.
5
+
6
+
###itunes-rsync.rb
7
+
Query a given iTunes playlist, build a scratch directory symlinking all files
8
+
of that playlist into it, then run `rsync` from the scratch directory to the
9
+
path given.
10
+
11
+
**Note:** `rsync`'s `--delete` option is used, so it will delete any files in
12
+
the given path that are not found in the playlist.
13
+
14
+
Usage: `ruby itunes-rsync.rb "ipod (auto)" /Volumes/music/iTunes/`
15
+
16
+
###playlist_album_shuffle.rb
17
+
Query a given iTunes playlist, organize all tracks into albums, shuffle the
18
+
albums, and then print the filename of each track in each album (in its
19
+
original track order) to STDOUT, relative to the path given.
20
+
21
+
Mimics the album shuffle functionality of iTunes and older iPods and can be
22
+
used to create a few album-shuffled `.pls` playlists of a given list of tracks
23
+
for players that don't natively support album shuffle.
24
+
25
+
**Note:** The path for the second argument is the path relative to all media as
26
+
it would be mounted by the player. Nothing is saved to that path and the
27
+
output is all done to STDOUT.
28
+
29
+
Usage: `ruby playlist_album_shuffle.rb "ipod (auto)" /mnt/SD1/iTunes/ > /Volumes/AK100/album\ shuffle\ 1.pls`
30
+
