2025 Linux Admin - Curl and Wget
URL Referenced - https://www.comptia.org/en-us/certifi...
In this video, I demonstrate how to use curl and wget in Linux to download and inspect web content directly from the command line. These tools are powerful for testing connectivity, grabbing web pages, and even automating tasks — but they should always be used responsibly. I also explain why recursively downloading sites without caution can unintentionally act like a denial-of-service (DoS) attack.
Commands Covered
man curl / man wget – Explore the manual pages for available options.
curl [URL] – Fetch web content directly in the terminal.
curl [URL] | wc -l – Count the number of lines returned by a web page.
wget [URL] – Download a web page and save it to a local file.
cat index.html – View the contents of the downloaded page.
