Download file with powershell

That is normally forbidden by webservers. Then you could parse the output and ask for specific files to be downloaded or all of them. But I dont see any straight-forward way. This works fine but I cannot step through this content. When I put this content through a foreach loop it dumps every line at once. If I save it to a file then I can use System. File::ReadLines to steps through line by line but that only works if I download the file. How can I accomplish this without downloading the file?

You can't parse text files with Invoke-WebRequest. If the text file is unstructured you can parse it with regex. More information about using regex in PowerShell can be found here and here. I am trying to download files from a site, sadly they are be generated to include the Epoch Unix timestamp in the file name. Now as I am unable to replace the Epoch Unix timestamp portion of the file name with a wild card, I was wondering if there was a way to do the download based on the date modified field of the file?

Thanks for this. I plan to use this along with task scheduler to download a fresh file every week. However, the new file overwrites the older one. Is there a way to preserve the older file as well? Ken - You should be able to relatively easily - however, you'd have to download it first, since you can't get the file properties until you download it.

You could download it to a temp location, grab the LastWriteTime stamp and parse it to create your new name. Sumit - You have a similar situation. You'll also need to manage the old copies so you don't fill up your disk. Your email address will not be published. Notify me of followup comments via e-mail.

NET framework enables almost unlimited possibilites inside the scripting realm.

This blessing can equally be a curse as things can get complicated. This post will describe three methods for downloading files using PowerShell - weighed up with their pros and cons. Today's testing is not highly scientific. The point is to show the difference in execution time and performance. The test setup consists of PowerShell 4 running on Windows 8.

The scripts will be executed 10 times each with the average displayed as the result. The first and most obvious option is the Invoke-WebRequest cmdlet. It is built into PowerShell and can be used in the following method:. With the cmdlet already available it is super easy to get started and use. Integration with Write-Progress is handy while watching paint dry scripts run assuming you know the total file size. On Windows 10, there are two aliases available for the Invoke-WebRequest cmdlet: curl and wget.

So, to download a file from the Internet website, you can use a shorter command. Instead of typing a full cmdlet name, you can use for example :.
