Wget and curl functionality via PowerShell on a Windows system

If you are accustomed to using the wget or cURL utilities on Linux or Mac OS X to download webpages from a command-line interface (CLI), there is a Gnu utility, Wget for Windows , that you can download and use on systems running Microsoft Windows. Alternatively, you can use the Invoke-WebRequest cmdlet from a PowerShell prompt, if you have version 3.0 or greater of PowerShell on the system. You can determine the version of PowerShell on a system by opening a PowerShell window and typing $psversiontable. E.g., in the example below from a Windows 10 system, the version of PowerShell is 5.1.15063.674.

PS C:\Users\public\documents>

If you have version 3.0 or later, you can use wget or curl as an alias for the Invoke-WebRequest cmdlet, at least up through version 5.x. E.g., if I want to download the home page for the website example.com to a file named index.html, I could use the command wget -OutFile index.html http://example.com at a PowerShell prompt. Or I could use either of the following commands, instead:

curl -OutFile index.html http://example.com
Invoke-WebRequest -OutFile index.html http://example.com

If you don't want to download the page to the system, but just want to see the header information for the page. You can just specify the URL for the page as shown below.
