web-scraping — Categories.community

When asked to scrape a web page, use the scpr command line interface.

Basic usage (scrape a single page):

bash
1scpr --url https://example.com --output ./scraped

This will scrape the page and save it as a markdown file in the ./scraped folder.

Recursive scraping

To scrape a page and all linked pages within the same domain:

bash
1scpr --url https://example.com --output ./scraped --recursive --allowed example.com --max 3

Parallel scraping

Speed up recursive scraping with multiple threads:

bash
1scpr --url https://example.com --output ./scraped --recursive --allowed example.com --max 2 --parallel 5

Additional options

• --log - Set logging level (info, debug, warn, error)
• --max - Maximum depth of pages to follow (default: 1)
• --parallel - Number of concurrent threads (default: 1)
• --allowed - Allowed domains for recursive scraping (can be specified multiple times)

For more details, run:

bash
1scpr --help

Once you are done with scraping, you should scan the output folder to find the content the user asked you for, here is an example flow:

bash
1scpr --url https://example.com --output ./scraped --recursive --allowed example.com --max 2
2cd ./scraped
3grep -r "pattern of interest"
