Whoami Tool Check — Identity & Access Verifier

Extended identity verification: confirm the current user matches an expected role, verify sudo/root access, check group membership for specific capabilities, and audit user-level access for security-sensitive operations.

Quick Start

# Verify current user
whoami-tool-check

# Check if current user has sudo access
whoami-tool-check --sudo

Usage

whoami-tool-check [OPTIONS]

Options:
  --sudo          Check if user has sudo/root access
  --role ROLE     Verify user belongs to a role group (sudo, docker, admin, etc.)
  --capabilities  List all accessible system capabilities
  --audit         Full user audit: uid, gid, groups, sudo, shell, home
  --json          Output as structured JSON
  --check-user USER   Check if a specific user exists and their details

Examples
