pashash

CLI utility for calculating MD5 hashes of files, written in Pascal (more hash algorithms coming soon).

Features

• Calculate MD5 hashes for single file or all files in directory
• Output to console or file
• No subdirectories processing
• Simple and fast

Installation

Requirements

• Free Pascal Compiler (FPC) 3.2+
• make

Build from source

git clone https://github.com/anmitalidev/pashash
cd pashash
make

The compiled binary will be placed in bin/pashash

Install system-wide (optional)

sudo make install

Usage

pashash [OPTIONS]

Options

• --version - Show version information
• -d <dir> - Process all files in directory
• -f <file> - Process single file
• -o <file> - Output file (if omitted, prints to console)

Examples

Process all files in current directory, output to console:

pashash -d .

Process all files in specific directory, save to file:

pashash -d /path/to/dir -o hashes.txt

Calculate hash for single file:

pashash -f document.pdf

Calculate hash for single file and save to file:

pashash -f document.pdf -o hash.txt

Output format

Each line contains filename and its MD5 hash separated by space:

file1.txt d41d8cd98f00b204e9800998ecf8427e
