Is there an equivalent of
curl in PowerShell? Does it have some similar built-in capability or is there a 3rd party cmdlet?
PowerShell 3.0 has the new command
As of Powershell 5.0, if not before,
curl is an alias for
PS> Get-Alias -Definition Invoke-WebRequest | Format-Table -AutoSize CommandType Name Version Source ----------- ---- ------- ------ Alias curl -> Invoke-WebRequest Alias iwr -> Invoke-WebRequest Alias wget -> Invoke-WebRequest
To use the unaliased command ...
PS> Invoke-WebRequest -Uri https://localhost:443/ PS> Invoke-WebRequest -Uri https://www.google.com
So return several properties of the request as follows ...
PS> Invoke-WebRequest -Uri https://www.google.com StatusCode : 200 StatusDescription : OK Content : <!doctype html><html itemscope="" itemtype="http://schema.org/WebPage" lang="en-AU"><head><meta content="text/html; charset=UTF-8" http-equiv="Content-Type"><meta content="/images/branding/googleg/1x/... RawContent : HTTP/1.1 200 OK X-XSS-Protection: 1; mode=block X-Frame-Options: SAMEORIGIN Vary: Accept-Encoding
... or just the content ...
PS> Invoke-WebRequest -Uri https://www.google.com | Select-Object -ExpandProperty Content <!doctype html><html itemscope="" itemtype="http://schem[etc ...]
The equivalent aliased commands are ...
PS> curl -Uri https://www.google.com PS> curl -Uri https://www.google.com | Select-Object -ExpandProperty Content
Leveraging Powershell defaults and other aliases you could shorten the commands to
PS> curl https://www.google.com ps> curl https://www.google.com | Select -ExpandProperty Content
... but I wouldn't recommend it. Verbose commands help others when reading your code.
Use of Aliases discouraged
As of Powershell 6.x "Core"
curl is no longer an alias for
Invoke-WebRequest (the alias
wget is also removed) . Instead use
PS> Get-Alias -Definition Invoke-WebRequest | Format-Table -AutoSize CommandType Name Version Source ----------- ---- ------- ------ Alias iwr -> Invoke-WebRequest
Curl is no longer an alias for Invoke-WebRequest (tested on Powershell 6.2.3), despite an apparent rejection of a motion in an RFC "to to remove the aliases curl and wget from Windows PowerShell".
That RFC notes "The wget/curl aliases were already removed from PowerShell Core so the problem [of having those aliases] was limited to Windows PowerShell."
In the conclusion the Powershell team also encourages users "to not rely on aliases in scripts".
As @v6ak has noted in the comments using
wget in PowerShell (5.0 or lower) can be a problem in: unintentionally invoking the real curl or wget if installed side-by-side; and, in any case, causes confusion.
It is recommended you upgrade Powershell "core" (6.x or above) in order to take advantage of the default encoding
utf8NoBOM, when using
Invoke-WebRequest (and many other text outputting commands). If one was doing this explicitly you could do something like:
Invoke-WebRequest ` -Uri https://raw.githubusercontent.com/fancyapps/fancybox/master/dist/jquery.fancybox.min.js ` | Select-Object -ExpandProperty Content ` | Out-File jquery.fancybox.min.js ` -Encoding utf8NoBOM
However, even when using a shorter, implicit, command ...
Invoke-WebRequest ` -Uri https://raw.githubusercontent.com/fancyapps/fancybox/master/dist/jquery.fancybox.min.js ` -OutFile jquery.fancybox.min.js
... encoding with
utf8NoBOM will be done (you can verify this, for example, by opening the saved file in Visual Studio Code and observing "UTF-8" in the status bar).
Files saved with
utf8NoBOM tend to cause fewer problems when traveling through various ecosystems. Of course, if you need some other encoding you can set some alternative explicitly.
In Powershell 5.0 and lower the
utf8NoBOM encoding was not available, let alone the default.
The excellent Command Line Kung Fu blog has a post where they compare curl, wget and the related PowerShell commands
In a nutshell:
Or, if your version of Powershell/.Net doesn't accept 2 parameters for
(New-Object System.Net.WebClient).DownloadString("http://www.example.com/hello-world.html") > "C:\hello-world.html"
You can also install Git for Windows, and then put the Git bin folder in your path. The Git install includes, among other things, curl.exe. After installing, just put
%programfiles(x86)%\git\bin in your PATH. Then you'll be able to use the curl command from the Windows Command Prompt or PowerShell console.
You can install cURL with Chocolatey and have curl available in PowerShell CLI or
the closest thing to
curl on windows is bits (Background Intelligent Transfer Service), which has some snippets ready for powershell.
If you’re one of these people – HAPPY NEW YEAR! 🙂 Windows 10 Insider build 17063 and later now include the real-deal curl and tar executables that you can execute directly from Cmd or PowerShell.
On PowerShell you need to run explicitly
curl is an existing alias
This command should work:
Invoke-WebRequest -UseBasicParsing -Uri http://example.com/
It's part of Microsoft.PowerShell.Utility since PowerShell 3.0.
