Binary file downloaded as text

The most common comparative tool to cURL is wget. As we discussed, one of the most useful thing to do with curls is to download a file with cURL. You simply use this format:. If you wanted to output it to a file, you just add -o to the command line with a target file name note: that is a lower case o :. To download a binary file, we can use the -O parameter which pulls down the content exactly as the source file specified dictates, including the name as such:.

To do that, type the following instead:. As always, when working on the command line, you will need to type the ENTER key after the command before PowerShell will act on your instructions.
