checksum

An utility to quick compare shasum output files from directories

Dependencies

• Python >= 3.2

Generating SHASUM files

First you need to create 2 shasum files with different directories, if you don't know how, you can do it with this bash script:

find {directory} -type f -exec shasum -a 256 {} \; > {output_file}

This command will generate a file using the algorithm SHA256 to compute recursively each file in the specified directory

How to use this tool

Syntax

python3 checksum.py --prod={checksum_file_for_directory_1} --resp={checksum_file_for_directory_2} --prefix1={prefix_from_prod_file} --prefix2={prefix_from_resp_file} --out={output_file}

Running this command will generate an output file comparing both files named results.txt, opening this file will give information about which files are diferent or missing in one file or another.

The output files describes only the differences, and use a nomenclature to define what kind of difference has been detected.

[-1-] = the file is only present in directory 1
[-2-] = the file is only present in directory 2
[=/=] = the file is present in both files, but the content is different.

Parameters

	--file1 : Specify the first SHASUM filename to compare
	--file2 : Specify the second SHASUM filename to compare
	--prefix1 : the directory prefix used to compare files structures in file1
	--prefix2 : the directory prefix used to compare files structures in file2
	--out : Specify a custom output filename (Optional)

TO-DO

• Improve the speed of the tool.
