Curl Command In Windows
Installing cURL Command Line Tool on Windows – Oracle
Installing the cURL Command-Line Tool on Windows
This tutorial shows you how to access Oracle Messaging Cloud
Service via the REST interface by using the cURL command-line tool. cURL is free, open software that runs under various operating systems.
This tutorial demonstrates cURL on a Windows 64-bit
operating system that is enabled for the secure sockets layer (SSL). The authentication aspects of the Messaging
Cloud Service require an SSL-enabled environment.
Your first task is to install the appropriate version of cURL
for your SSL-enabled environment.
There is an ordered series of steps to follow to install cURL
on Windows. There are two libraries to install and they must
be installed before cURL will work with SSL. Also, they must be
installed in this order to work. Do not skip
the step to install a recent certificate.
In your browser, navigate to the cURL welcome page at and
click Download.
On the cURL Releases and Downloads page, click the link for the SSL-enabled version for your computer’s operating system, download the zip file, and install
it in a new folder on your computer.
The cURL website offers a wizard to find the appropriate version for your
computer’s operating system.
For this tutorial, the 64-bit generic, SSL-enabled version for Windows is selected.
Install recent CA Certificates. Do not skip this step.
Download, a recent copy of valid CERT
files, from
Copy it to the same folder where you placed
and rename it
Invoke from a command window (in Windows, click Start > Run and then enter “cmd” in the Run dialog box).
You can enter curl –help to see a list of cURL commands.
How To Use cURL On Windows 10 – AddictiveTips
cUrl is a command line tool that Linux users are more than familiar with. If you once used Linux and have since moved to Windows, or if you use both Linux and a Windows machine, you likely miss this little tool but there’s no reason to. You can use cUrl on Windows 10, and older versions.
cUrl On Windows 10
If you want to use cUrl on Windows 10, you have two options. Check your Windows 10 build and if you have anything older than 1706, proceed as follows.
You will have to download cUrl from the official website. The Windows version is at the bottom of the download page. You want to download the generic zipped version. Extract the zipped file and inside the bin folder, you will find the file. Open Command Prompt in this folder, and run whatever command it is you want.
Since it’s time consuming to have to cd to the bin folder each time you want to use cUrl, it’s a good idea to add the path to your Path Environment Variables. This will allow you to run cUrl from anywhere.
If your Windows 10 build is 17063, or later, cUrl is included by default. All you need to do is run Command Prompt with administrative rights and you can use cUrl. The is located at C:\Windows\System32. If you want to be able to use cUrl from anywhere, consider adding it to Path Environment Variables.
cUrl On Windows 7, 8/8. 1
On Windows 7 and 8/8. 1, the same process as that for Windows 10 builds older than 17063 will apply. You need to download cUrl from official website linked in the previous section, and run it. To make it easier to use, you can add it to Path Environment Variables.
Using cUrl
If you’ve added the cUrl EXE to Path Environment Variables, you can run a cUrl command from anywhere from Command Prompt. If you haven’t added it to Path Environment Variables, you need to first open Command Prompt with administrative rights (Windows 10, build 1706 and later), and then run the command.
For older Windows 10 builds, and for Windows 7 and 8/8. 1, you need to first cd to the folder with the cUrl EXE, and then run a command.
Microsoft gives users plenty of reason to upgrade to Windows 10. In addition to adding cUrl by default, it also includes Tar now. Tar lets you create archives, and extract them without needing additional tools. If that isn’t reason enough to upgrade, there’s also the fact that Office 2019 will only run on a Windows 10 PC.

cURL (pronounced like “curl”, /kɜːl/[6]) is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various network protocols. The name stands for “Client URL”, [7] which was first released in 1996. [8]
History[edit]
cURL was first released in 1996. [8] It was originally named get and then became urlget before adopting the current name of cURL. [9][10] The original author and lead developer is the Swedish developer Daniel Stenberg, who created cURL because he wanted to automate the fetching of currency exchange rates for IRC users. [2]
libcurl[edit]
libcurl is a free client-side URL transfer library, [11] supporting cookies, DICT, FTP, FTPS, Gopher, HTTP/1[12] (with HTTP/2 and HTTP/3 support), HTTP POST, HTTP PUT, HTTP proxy tunneling, HTTPS, IMAP, Kerberos, LDAP, MQTT, POP3, RTSP, RTMP, SCP, SMTP, and SMB. The library supports the file URI scheme, SFTP, Telnet, TFTP, file transfer resume, FTP uploading, HTTP form-based upload, HTTPS certificates, LDAPS, proxies, and user-plus-password authentication. [13]
The libcurl library is portable. It builds and works identically on many platforms, including AIX, AmigaOS, Android, BeOS, BlackBerry Tablet OS and BlackBerry 10, [14] OpenVMS, Darwin, DOS, FreeBSD, HP-UX, HURD, iOS, IRIX, Linux, macOS, NetBSD, NetWare, OpenBSD, OS/2, QNX Neutrino, RISC OS, Solaris, Symbian, Tru64, Ultrix, UnixWare, and Microsoft Windows.
The libcurl library is free, thread-safe and IPv6 compatible. Bindings are available for more than 50 languages, including C/C++, Java, PHP and Python. [16]
The libcurl library supports GnuTLS, mbed TLS, NSS, gskit on IBM i, SChannel on Windows, Secure Transport on macOS and iOS, SSL/TLS through OpenSSL, Boringssl, libressl, AmiSSL, wolfSSL, BearSSL, Mesalink and rustls. [citation needed]
cURL[edit]
cURL is a command-line tool for getting or sending data including files using URL syntax. Since cURL uses libcurl, it supports every protocol libcurl supports. [13]
cURL supports HTTPS and performs SSL certificate verification by default when a secure protocol is specified such as HTTPS. When cURL connects to a remote server via HTTPS, it will obtain the remote server certificate, then check against its CA certificate store the validity of the remote server to ensure the remote server is the one it claims to be. Some cURL packages are bundled with CA certificate store file. There are several options to specify a CA certificate such as –cacert and –capath. The –cacert option can be used to specify the location of the CA certificate store file. In the Windows platform, if a CA certificate file is not specified, cURL will look for a CA certificate file name “” in the following order:
Directory where the cURL program is located.
Current working directory.
Windows system directory.
Windows directory.
Directories specified in the%PATH% environment variables. [17]
cURL will return an error message if the remote server is using a self-signed certificate, or if the remote server certificate is not signed by a CA listed in the CA cert file. -k or –insecure option can be used to skip certificate verification. Alternatively, if the remote server is trusted, the remote server CA certificate can be added to the CA certificate store file.
Examples[edit]
Basic use of cURL involves simply typing curl at the command line, followed by the URL of the output to retrieve:
cURL defaults to displaying the output it retrieves to the standard output specified on the system (usually the terminal window). So running the command above would, on most systems, display the source-code in the terminal window. The -o flag can be used to store the output in a file instead:
$ curl -o
More options that change the tool’s behavior are available.
