In terminal, merging multiple folders into one.
- by Josh Pinter
I have a backup directory created by WDBackup (western digital external HD backup util) that contains a directory for each day that it backed up and the incremental contents of just what was backed up.
So the hierarchy looks like this:
20100101
My Documents
Letter1.doc
My Music
Best Songs Every
First Songs.mp3
My song.mp3 # modified 20100101
20100102
My Documents
Important Docs
Taxes.doc
My Music
My Song.mp3 # modified 20100102
...etc...
Only what has changed is backed up and the first backup that was ever made contains all the files selected for backup.
What I'm trying to do now is incrementally copy, while keeping the folder structure, from oldest to newest, each of these dated folders into a 'merged' folder so that it overrides the older content and keeps the new stuff.
As an example, if just using these two example folders, the final merged folder would look like this:
Merged
My Documents
Important Docs
Taxes.doc
Letter1.doc
My Music
Best Songs Every
First Songs.mp3
My Song.mp3 # modified 20100102
Hope that makes sense.
Thanks,
Josh
