René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Invoke-WebRequest allow option to preserve orginal filename (even after redirect)","articleBody":"# Summary of the new feature/enhancement\r\n\r\nAs a user downloading from an aka.ms URL, I want the filename of my downloaded file to automatically match that of the source file. \r\n\r\nE.g. on Linux, if I do \r\n```\r\nwget https://aka.ms/downloadazcopy-v10-linux\r\n```\r\n\r\nIt just works. The output file is created, and it has the right name. E.g. when the aka.ms link points to a file name AzCopy_linux-amd64-10.0.9.tar.gz, that's the name I end up with on disk.  When someone updates the aka ms link to point to, say AzCopy_linux-amd64-10.2.0.tar.gz, then I can run the same command as before, and this time I automatically get the updated name.\r\n\r\nThis is useful for cases where the filename conveys useful information (such as the version).\r\n\r\nBut in PowerShell, I can't automatically use the file's existing name. I have to specify a name. But because the URL is a redirect, via aka.ms, I don't actually know the name of the download file in advance. So I can't specify a meaningful name (e.g. I can't include the version number). I still get the file, but I lose any information that was in its original name\r\n\r\n# Proposed technical implementation details (optional)\r\n\r\nAdd a new command line parameter, called something like `PreserveFilename'.  So the PowerShell equivalent of the Linux command above would be\r\n```\r\nInvoke-WebRequest https://aka.ms/downloadazcopy-v10-linux --PreserveFilename\r\n```","author":{"url":"https://github.com/JohnRusk","@type":"Person","name":"JohnRusk"},"datePublished":"2019-05-27T22:22:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/9742/PowerShell/issues/9742"}
