Using Google Music Manager in Linux from the command line
You can.
Take a look at these to scripts:
- http://development.giaever.org/pastebin/Ubuntu/google-musicmanager/install-gmm-headless.sh
- http://development.giaever.org/pastebin/Ubuntu/google-musicmanager/gmm-headless-script.sh (Visit links in direct order to understand them.)
Hope they are useful. Read comments. Remember to edit: «GMAILUSER -p PASSWORD -s /path/to/music -m SERVERNAME» with you own data. (SERVERNAME could be whatever. Its just a name so you can identify your server from your Google-login.)
Type $HOME/gmm-headless-script.sh in terminal to start sync.
Edit: some systems won't already have Xvfb installed, and on those you can fix this with sudo apt-get install xvfb.
This is a duplicate of "uploading music automatically with Google Music on a Linux server". To quote the answer I've just provided there...
I think what you appear to be looking for is https://github.com/thebigmunch/gmusicapi-scripts - a set of python scripts to upload, download or bi-directionally sync tracks. This, in turn, draws from https://github.com/simon-weber/Unofficial-Google-Music-API should you wish to use these python libraries for your own projects.
