From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Trying to recreate a version control system for my music collection, with one crucial difference ... 🤯 (feddit.org)

I want to have a mirror of my local music collection on my server, and a script that periodically updates the server to, well, mirror my local collection.

But crucially, I want to convert all lossless files to lossy, preferably before uploading them.

That's the one reason why I can't just use git - or so I believe.

I also want locally deleted files to be deleted on the server.

Sometimes I even move files around (I believe in directory structure) and again, git deals with this perfectly. If it weren't for the lossless-to-lossy caveat.

It would be perfect if my script could recognize that just like git does, instead of deleting and reuploading the same file to a different location.

My head is spinning round and round and before I continue messing around with find and scp it's time to ask the community.

I am writing in bash but if some python module could help with it I'm sure I could find my way around it.

TIA

additional info:

  • Not all files in the local collection are lossless. A variety of formats.
  • The purpose of the remote is for listening/streaming with various applications
  • The lossy version is for both reducing upload and download (streaming) bandwidth. On mobile broadband FLAC tends to buffer a lot.
  • The home of the collection (and its origin) is my local machine.
  • The local machine cannot act as a server

I don't think git is the right tool for this. It's designed for text files, not binary. Also, there's no need for version control here. Git won't store diffs of binary files, so if a file changes (even the slightest change like an mp3 tag) it will keep a full copy of the old file.
OP wants to sync, so I would use rsync here. It will be way faster and efficient. If you want to know what rsync did, you can keep a log file of it's output.
