I needed to download OneGet for the previous post. I had the URL, but rather than open a browser as I would usually do I used PowerShell to download the file:
|
1 |
PS> Invoke-WebRequest http://oneget.org/oneget.zip -OutFile oneget.zip |
Nifty, eh! If you omit the -OutFile you get the headers and such:
|

Lastly, just for kicks, to get all elements of a certain tag from a website:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |

Got to love it when you can do such cool things with Windows/ PowerShell so easily! A few years ago I could have barely imagined such a thing would be possible on Windows.
Update: While I am at it, here’s how you can quickly download a bunch of files from a website. In this case I want to download all mp3 files from a music website (for example purposes!). Through trial and error I know the links have the text “download” in them, so I can filter for such links and then download each of these to an appropriate file:
|
1 |
(Invoke-WebRequest http://downloadming.nu/badlapur-2015-mp3-songs).Links | ?{ $_.outerText -eq "download" } | select href | %{ Invoke-WebRequest $_.href -OutFile $(Split-Path -Leaf $_.href) } |
Or a variant:
|
1 2 |
# I expand the "href" hashtable beforehand in this case (Invoke-WebRequest http://downloadming.nu/badlapur-2015-mp3-songs).Links | ?{ $_.outerText -eq "download" } | select -ExpandProperty href | %{ Invoke-WebRequest $_ -OutFile $(Split-Path -Leaf $_) } |
If you use a different site you’ll have to modify the filters accordingly, but it’s pretty straight-forward …
