Set Operations on File Directories.

Use some basic Set Operations to analyse and compare the file names in 2 or more given directories.

# Background

Several times over the past couple of years I've had to work out the difference between 2 folders in terms of files.

Each time it's manually looking > unix utilities > ad-hoc scripts.

This little tool should permanently solve this problem.

# Install

```

pip3 install file-dir-set-ops --upgrade

```

# Usage

## Data

![sets](images/sets.gif)

## Union

![union](images/union.gif)



(In **A** OR **B** OR **C**)

```

file-dir-set-ops --operation union --dir-paths tests/data/a tests/data/b tests/data/c

a.txt

b.txt

c.txt

file.txt

```

## Intersection

![union](images/intersection.gif)



(In **A** AND **B** AND **C**)

```

file-dir-set-ops --operation intersection --dir-paths tests/data/a tests/data/b tests/data/c

file.txt

```

## Relative Complement (Set Difference)

(In **A** AND Not in **B** OR **C**)

```

file-dir-set-ops --operation complement --dir-paths tests/data/a tests/data/b tests/data/c
