Which non-interactive command-line tool is used to retrieve files via HTTP, HTTPS, and FTP and can be scripted?

• A. GNU Wget
• B. WhatWeb
• C. lbd
• D. Halberd

Answer: (A)

Focusing on tools that fetch files from the web in an automated, non-interactive way is about scriptable download utilities. GNU Wget fits this role perfectly: it can retrieve files over HTTP, HTTPS, and FTP without any browser involved, and its command-line interface is designed to be embedded in scripts, batch jobs, or cron tasks. It also offers features that are handy in automation, like resuming downloads, following redirects, and recursive or mirrored downloads, all without user interaction. The other tools are aimed at different tasks. WhatWeb is a web technology fingerprinting tool that analyzes a site to reveal technologies in use, not primarily for downloading files. The remaining options are oriented toward discovery or vulnerability assessment rather than bulk, scriptable file retrieval, so they don’t provide the same straightforward download capabilities as GNU Wget.
