This small script is used to merge two directories which may overlap in files (mostly because they were originally copies which have since diverged).

Example

Layout:

dir1/
    file.txt
    photo.jpg
    something.doc

dir2/
    newfile.txt
    photo.jpg
    something.doc

Now, assume that photo.jpg is the same (same content, same file type) in both directories, but something.doc is different. Run:

mergedirs dir1/ dir2

And you will get:

dir1/
    something.doc

dir2/
    file.txt
    newfile.txt
    photo.jpg
    something.doc

Merge will never cause any data loss, only remove extra copies of your files.

There are a few helpful options, which you can read about using mergedirs --help.

Where can I get it?

Github as usual.
