Koodilistaus:Jamoget

<metadesc content="Bash-komentojono, joka lataa Jamendosta albumin Ogg Vorbis -muodossa ja panee sen sitten jakoon." /> Lataa tiedostona: [{{#file: jamoget}} jamoget]

Tämä Bash-komentojono lataa sille parametreina tai tiedostossa (nykyisessä hakemistossa oleva idlist-niminen tiedosto) listatut albumit Jamendosta Ogg Vorbis -muotoisina, ja pudottaa ne sen jälkeen Bittorrent-asiakasohjelman jakoon. Albumit tulee antaa pelkästään niiden tunnusnumeroilla, esimerkiksi näin: jamoget 42673 43733

Mikäli albumit luetellaan tiedostossa, ne tulee erotella toisistaan rivinvaihdoilla.

Komentojonon käyttöönotto vaatii melko varmasti mukailua hakemistoviittausten (CONFIGURATION-osio) osalta.

Tämä on oma muunnelmani Jamendon foorumilta löytyneestä alkuperäisteoksesta, jonka on luonut The Chilling Spirit. Alkuperäisen lisenssi on tuntematon, todennäköisesti kuitenkin vapaa.

# This will download album ZIP files from Jamendo directly. By default it gets Ogg Vorbis,
# remove the last parameter from the wget lines to get MP3
# It will then also grab the .torrent file, unzip the album and move the .torrent to your client's watch directory.
# Put the IDs of all the albums you want into a file called idlist, one id per line.
