Lynx Web Search

Overview

Use lynx as a fast text-only fallback for web search and page retrieval.

This skill focuses on two repeatable tasks:

1. Search engines from the terminal
2. Fetch a URL and save a readable dump in /tmp

When to Use

• Need quick web search from shell without GUI/browser automation
• Dedicated web tooling is unavailable
• Need plain-text output for analysis/summarization
• Need deterministic saved artifacts in /tmp

When NOT to use:

• JavaScript-heavy pages requiring interaction/login flows
• Visual testing or DOM inspection (use browser automation tools)

Quick Reference

Engine URL templates

Core lynx flags from man lynx

• -dump: render readable text and exit
• -source: dump raw source and exit
• -listonly: output links list only (good for extracting URLs)
• -accept_all_cookies: avoid cookie prompts
• -useragent=...: override UA when sites block default behavior

Implementation

1) Search any engine and save output to /tmp

engine="brave"          # google|brave|bing|yahoo|github|reddit|oldreddit
query="lynx cli usage"
q=$(python - <<'PY' "$query"
import sys, urllib.parse
print(urllib.parse.quote_plus(sys.argv[1]))
PY
)

case "$engine" in
  google)    url="https://www.google.com/search?q=$q" ;;
  brave)     url="https://search.brave.com/search?q=$q&source=web" ;;
  bing)      url="https://www.bing.com/search?q=$q" ;;
  yahoo)     url="https://search.yahoo.com/search?p=$q" ;;
  github)    url="https://github.com/search?q=$q&type=repositories" ;;
  reddit)    url="https://www.reddit.com/search/?q=$q" ;;
  oldreddit) url="https://old.reddit.com/search?q=$q" ;;
  *) echo "Unknown engine: $engine" >&2; exit 2 ;;
esac

out="/tmp/lynx-search-${engine}-$(date +%Y%m%d-%H%M%S).txt"
lynx -accept_all_cookies -dump "$url" | tee "$out"
printf "\nSaved: %s\n" "$out"

2) Fetch a given URL and save readable dump to /tmp

url="https://example.com"
out="/tmp/lynx-page-$(date +%Y%m%d-%H%M%S).txt"
lynx -accept_all_cookies -dump "$url" > "$out"
printf "Saved readable dump: %s\n" "$out"

3) Optional: save raw HTML/source to /tmp

url="https://example.com"
out="/tmp/lynx-source-$(date +%Y%m%d-%H%M%S).html"
lynx -source "$url" > "$out"
printf "Saved source dump: %s\n" "$out"

Common Mistakes

• Forgetting URL encoding for multi-word queries → use urllib.parse.quote_plus
• Assuming Google always works in text mode (often blocked/JS challenge)
• Using only one engine when blocked → retry with Brave/Bing/Yahoo/GitHub/old Reddit
• Not saving outputs → always write to /tmp/lynx-*.txt for traceability
• Expecting JS-rendered content from lynx → use browser automation for dynamic pages
