HashWalker

HashWalker

HashWalker is a simple command-line tool that recursively walks through a directory, calculates the MD5 hash of each file, and saves the results to a CSV file. It can also compare two CSV files generated by the tool to detect new, modified, or deleted files.

Features

• Walk through directories and subdirectories recursively
• Calculate MD5 hashes for each file
• Save file hashes to a CSV file
• Compare two CSV files to detect file changes

Usage

HashWalker accepts three command-line arguments:

• -dir: The directory you want to walk through and hash. When this flag is used, the tool will calculate file hashes and save them to a CSV file named "file_hashes.csv" in the current working directory.
• -baseline: The baseline CSV file for comparison. This file should contain file hashes generated by HashWalker.
• -csv: The second CSV file for comparison. This file should also contain file hashes generated by HashWalker.

To generate a CSV file with file hashes:

./hashwalker --dir=/path/to/directory

To compare two CSV files:

./hashwalker --baseline=baseline.csv --csv=comparison.csv

When comparing CSV files, HashWalker will print new, modified, or deleted files to the console.

Installation

To install and build HashWalker, make sure you have Go installed, and then run:

git clone https://github.com/yourusername/hashwalker.git
cd hashwalker
go build

This will create a binary named hashwalker in the current directory. You can move this binary to a directory in your PATH for easier access.
