Powershell command to download a file from internet

To do this, press Windows Key on your keyboard and type in powershell. Select Yes in the UAC window that pops up. Now, you need to copy the link of the file you want to download using PowerShell. Would I need to spin off another thread in order to accomplish this? A person after my own heart! I love computer hardware stores. It is indeed possible to do what you want to do.

Unfortunately, it will require a bit of a rewrite to your script. You will need to use System. HttpWebRequest instead of System. The GetResponse method returns an instance of the HttpWebResponse class that contains a contentLength property that will do what you need.

Well, this concludes another edition of Quick-Hits Friday. Join me tomorrow for the Weekend Scripter as I delve into the mysteries of creating a function to automate exporting history.

I would love you to follow me on Twitter and Facebook. If you have any questions, send email to me at scripter microsoft. See you tomorrow. Until then, peace. On Windows 10, you can use the built-in Invoke-WebRequest cmdlet to download files this cmdlet is available in all versions since PowerShell 3.

To download a file, you just need to specify its URL and the local folder in which to save the file:. Downloading the files does not require running the Windows console with Administrator permissions. If we prefer to avoid permission issues, for example, the commands will also work when opening the console with Admin permissions. Once we have the PowerShell window open, we only have to know the URL of the file that we want to download. Once we have it, we execute the following command in the PowerShell console to create a new instance and prepare the program to download the file from the Internet:.

Next we will use the DownloadFile method to download the file. 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.
