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

Union

(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

(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

a.txt
