Link Check

Validate internal and external links in blog posts.

Instructions

1. •

   Determine scope from $ARGUMENTS:

   • •If a file path is provided, check that specific post
   • •If --all flag is used, check all posts
   • •If --recent flag is used, check posts from the last 6 months
   • •Otherwise, ask the user what to check
2. •

   For the specified scope, extract and validate all links:

Internal Links

• •Links starting with / or relative paths
• •Links to /archive/... posts
• •Links to /courses/... pages
• •Links to /workshops/... pages

For each internal link:

• •Check if the target file exists
• •Report broken links with the source file and line number

External Links

• •Links starting with http:// or https://
• •YouTube embeds (plain URLs that get embedded)

For each external link:

• •Attempt to fetch the URL (HEAD request)
• •Report any that return 4xx or 5xx errors
• •Flag any HTTP links that should be HTTPS

1. •Generate a report:

## Link Check Report

### Summary
- Total links checked: X

   • •Suggesting the correct path
   • •Finding similar posts if the target was moved/renamed

• •Some external sites may block automated requests (false positives)
• •YouTube URLs are validated but not fetched (they're usually fine)
