Curl DOM of a web page

curl -s {url}
  • -s flag is to "silent" the progress bar printing.

DOM navigation

pup {selector}
  • pup: https://github.com/ericchiang/pup
    • to install: brew install pup
  • h1 is the css selector
    • it can be a tag name like h1
    • or it can be dom id like #id
    • or class name .class
  • text{} can fetch the text inside of the dom object
    • without this the output looks like <h1>Your case is actively reviewed by USCIS</h1>
    • with this the output looks like Your case is actively reviewed by USCIS
