llmfile

A file type classifier that mimics the Linux file utility by using LLM analysis of file headers and footers.

Installation

Install globally:

npm install -g .

Or use with npx (no installation required):

npx llmfile <file1> [file2] ...

Usage

export BEDROCK_API_KEY="your-bedrock-api-key"
llmfile <file1> [file2] ...

Or with npx:

export BEDROCK_API_KEY="your-bedrock-api-key"
npx llmfile <file1> [file2] ...

Examples

% llmfile index.js
index.js: JavaScript text, UTF-8 Unicode (node.js) text

% file index.js
index.js: a /usr/bin/env node script text executable, ASCII text

How it works

1. Reads the first 512 bytes (header) and last 512 bytes (footer) of each file
2. Converts the binary data to hexadecimal format
3. Sends the hex data to AWS Bedrock
4. Returns file type classification similar to the Linux file command
