scrapy: Create a spider (in project directory).
$ scrapy genspider ${spider_name} ${website_domain}
try on your machine
The given command is a Scrapy command used to generate a spider.
Scrapy is a Python framework for web scraping and building web crawlers. A spider is the main component of a Scrapy project, responsible for defining how to crawl a website, extracting data from it, and storing the scraped information.
The command is structured as follows:
scrapy
: The command-line tool used to execute Scrapy commands.genspider
: The specific command that tells Scrapy to generate a spider.${spider_name}
: This is a placeholder representing the desired name of the spider you want to generate. You need to replace${spider_name}
with your preferred name when running the command.${website_domain}
: This is another placeholder representing the domain or URL of the website you want to crawl. Again, you need to replace${website_domain}
with the actual domain or URL when running the command.
So, when you run the command, Scrapy will generate a spider file with the provided ${spider_name}
as the name and configure it to crawl the specified ${website_domain}
. The spider file will be created with basic structure and you can modify it later to define the crawling and scraping logic according to your requirements.

never run a command you are not sure if it is safe.
