FileInfo - Quick File Triage from the Command Line

During Blue Team CTFs and DFIR activities, I often found myself needing immediate access to file hashes and essential metadata. To streamline this process, I built FileInfo — a lightweight cross-platform toolkit (Bash and PowerShell) to quickly extract key information and generate IoCs from any file.

It provides filename, full path, size, timestamps, and multiple hashes (SHA256, SHA1, MD5) in a simple way perfect for fast triage and forensic workflows.
