- To download it, simply press 'Download'. Next, open the.zip file and enter to the folder called 'src.'. Inside the src folder you will find the curl executable file. At this point, you need to copy the executable file and paste it inside a local folder on your PC to be able to run the curl. NOTE: To get a better understanding of the.

- Use CURL for File Transfer Uploading files is quite simple, but the utility allows you to perform other actions, such as sending files to an ftp server. For this there is an option -T.

Curl -O Make sure the letter O is capitalized. After you type curl -O, just paste the URL of the file you want to download. Don’t include the “” either, that’s just an insertion point.

cURL is both a library and a command line utility written to handle the transfer of data using many different protocols. It is scriptable and extremely versatile but this makes it quite complicated.
If you are looking for a utility to download a file then please see wget. We would recommend reading our wget tutorial first and checking out
man wget
before using curl as wget is more user-friendly in most cases. However, for more complex operations you cannot beat cURL. It has over 100 different command line options many of which can be used in combinations. It is very powerful and can even handle cookies, forms and ssl. However it can also be used for some very simple tasks that you will find useful. In this tutorial we will concentrate on the things that cURL can do that wget can’t.The Basics
At its most basic you can use cURL to download a file from a remote server. To download the homepage of
example.com
you would use curl example.com
. cURL can use many different protocols but defaults to HTTP if none is provided. It will, however, try other protocols as well and it can intelligently guess which protocol to use if hints are given. For instance, if you use curl ftp.example.com
it will automatically try the FTP:// protocol.If however you want to help cURL to choose the right protocol then prefix the url with the protocol such as
curl http://example.com
or curl ftp://example.com
.Setting the output file
If you want to give the downloaded file a different name you would use the -o option. For example.
curl -o filename.tar.gz http://filename-4.0.1.tar.gz
If you don’t set the output file it will display it to the console.
Viewing the complete request and response
Quite often when learning curl you will either get an unexpected output or no output at all. The
-v
option is very useful in these situations. The -v
option displays all the information in the request sent to the remote server and the response it receives.Saving a 301-redirected file
If a site has WordPress® installed for example and they are using 301 redirects you will by default download the redirect response only. To ensure you follow the redirects and get the final file you will need to use the -L option. If you try
curl google.com
you will just get the redirect page, if you now try curl -L google.com
you will get the page you were after.Nothing returned
If you use curl and don’t get any return or an error you can try the -v option. This will show all the headers. The header may have a 301 redirect code in it but no body to display. If this is the case you can use the -L option to follow the redirect.
Those are the basics of cURL. We will now move on to the intermediate levels of cURL usage.
Viewing only the response headers for debugging
When you are writing a script using cURL sometimes you will want to view the response headers only without seeing the data or the request. Having a clean view of what is happening, without all the data to obscure things, can be helpful with debugging. To do this you would use the
-I
option. For instance in the previous example with Google® we could use curl -I google.com
Skipping SSL checks
When connecting to a remote server that has a self signed certificate you will want to skip the ssl checks. To do this use the
-k
option. For example curl -k https://google.com

Setting the user agent
The
-A
option allows you to set the user agent. For example curl -A 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0' -L google.com
.Rate Limiting
To avoid hitting the remote server hard you can limit the download rate you will use. The command to do this is
--limit-rate
and use like this --limit-rate 100k
.FTP Login
To set the username and password you can use the –user username:password option. How to download instagram photos.
FTP upload and download
To download you just need to use the basic curl command but add your username and password like this
curl --user username:password -o filename.tar.gz ftp://domain.com/directory/filename.tar.gz
.To upload you need to use both the –user option and the -T option as follows.
curl --user username:password -T filename.tar.g ftp://domain.com/directory/
To delete a file from the remote server.
curl --user username:password -X 'DELE filename.tar.gz' ftp://domain.com/
For details on the
-X
option please see the next section.Sending POST requests and different FTP Commands
The -X command allows you to send custom commands to the receiving server. For HTTP this could be a POST request or WebDAV’s copy or move. For FTP you can use the
-X
option to send other commands instead of the default file LIST, like in the previous section's example of using -X
to send the DELE command to an FTP server. However, this can also be used to send full POST data to an HTTP server.If the page you wanted to POST to had a form like this:
you could submit the form request using
curl -X POST --data 'name=barrym&button1=OK' http://www.example.com/test.php
.Using Cookies
If the server you are connecting to requires a cookie then you can send it using
curl -b cookiefile.txt http://example.com

Sending custom headers
If you need to send a custom header to the server you would use the
-H
option like thiscurl -H 'Accept: text/html' http://domain.com
. Which would set the content type to text/html.Verifying an SSL Certificate
If you want to verify that your SSL cert is valid without using your browser and run into potential caching issues then use
curl --cacert mycert.crt https://domain.com
. This is also useful if you need to validate the connection to ensure that you are connecting to the right server.The certificate must be in PEM format. If the optional password is not specified, it will be queried for on the terminal. Note that this option assumes a “certificate” file that is the private key and the private certificate concatenated.
Limiting the connection timeout time
Sometimes you will want the connection to time out quickly if it can’t make the connection within a certain time frame. The option to use to do this is –connect-timeout. This only affects the connection time so once you are connected it no longer applies.
curl --connect-timeout 5 http://domain.com
Finding out more
As stated in the introduction there are over 100 command line options for cURL so we have just covered some of the most commonly used ones in our experiences. cURL can do a lot more than described above and
man curl
is a good place to start to find out more. If you prefer a web-based reference then http://curl.haxx.se/docs/faq.html is the authoritative one.Was this article helpful?

Indesign cc 2017 mac direct download. cURL is one of the most powerful tool for testing HTTP requests and responses. Most developers use
curl
to interact with HTTP APIs or to test a website.Starting from version 7.43.0 cURL (and
libcurl
) supports HTTP/2. You can perform a request using the HTTP/2 protocol passing the --http2
flag:However, in order to support HTTP/2, cURL must be linked to
nghttp
and the default cURL version shipped with Mac OS X does not. As a result, if you try to pass the --http2
flag you'll receive the following error:To solve the issue and use cURL with HTTP/2 in Mac OS X your need to recompile cURL. This is a very easy task if you use Homebrew. Thanks to this PR you can reinstall cURL via Homebrew and pass the
--with-nghttp2
flag to add the HTTP/2 support along with the necessary dependencies.Almost done. By default, Homebrew will not replace the
curl
binary shipped with Mac OS X, therefore you need to explicitly 'link' it if you want to use the new version without specifying the entire path to the binary (which by the way is /usr/local/Cellar/curl/7.46.0/bin/curl

curl
location should now be:You can also confirm the version and the custom flag using the command
brew info curl
:If it's still
/usr/bin/curl
then make sure cURL was properly installed via Homebrew and you restarted your shell.Instructions
To recap, here's the list of commands to compile and install cURL with HTTP/2 support in Mac OS X using Homebrew:
A special thanks to Daniel Stenberg for cURL, and to
