Bash – rsync : Recursively sync all files while ignoring the directory structure

bashrsync

I am trying to create a bash script for syncing music from my desktop to a mobile device. The desktop is the source.

Is there a way to make rsync recursively sync files but ignore the directory structure? If a file was deleted from the desktop, I want it to be deleted on the device as well.

The directory structure on my desktop is something like this.

    Artist1/
        Artist1/art1_track1.mp3
        Artist1/art1_track2.mp3
        Artist1/art1_track3.mp3
    Artist2/
        Artist2/art2_track1.mp3
        Artist2/art2_track2.mp3
        Artist2/art2_track3.mp3
    ...

The directory structure that I want on the device is:

    Music/
        art1_track1.mp3
        art1_track2.mp3
        art1_track3.mp3
        art2_track1.mp3
        art2_track2.mp3
        art2_track3.mp3
    ...

Simply:

rsync -a --delete --include=*.mp3 --exclude=* \
    pathToSongs/Theme*/Artist*/. destuser@desthost:Music/.

would do the job if you're path hierarchy has a fixed number of level.

WARNING: if two song file do have exactly same name, while on same destination directory, your backup will miss one of them!

If else, and for answering strictly to your ask ignoring the directory structure you could use bash's shopt -s globstar feature:

shopt -s globstar
rsync -a --delete --include=*.mp3 --exclude=* \
    pathToSongsRoot/**/. destuser@desthost:Music/.

At all, there is no need to fork to find command.

Recursively sync all files while ignoring the directory structure

For answering strictly to question, there must no be limited to an extension:

shopt -s globstar
rsync -d --delete sourceRoot/**/. destuser@desthost:destRoot/.

With this, directories will be copied too, but without content. All files and directories would be stored on same level at destRoot/.

WARNING: If some different files with same name exists in defferents directories, they would simply be overwrited on destination, durring rsync, for finaly storing randomly only one.
