Install and Set Up kubectl. The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters.You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs. we use Mac OS X 10.8 and Xcode 4.5.2. Here we try now to create our first simple (Cocoa Application) example with the curl-library. We will download an file with this library and place the downloaded file to a special place. Enclosed I'll send you the code we use until now.
We often have to download various files from the Internet, for example, executable program files, script files, archives with source codes. But it is not always necessary to do this through the browser. In many situations it is much easier to perform all actions through the terminal. Because this way you can automate the process. On the other hand, webmasters from time to time have to test the availability of websites, check the sent and received headers, and more.
To solve such problems and tasks of such a circle, you can use the curl utility. It allows you to solve a much wider range of tasks, among which even an imitation of user actions on the site. In this article we will look at how to use curl, what it is and why we need this program.
What is CURL?
In fact, curl is more than just a command line utility for macOS, Linux or Windows. This is a set of libraries that implement the basic capabilities of working with URL pages and file transfer. The library supports working with protocols: FTP, FTPS, HTTP, HTTPS, TFTP, SCP, SFTP, Telnet, DICT, LDAP, as well as POP3, IMAP and SMTP. It is great for simulating user actions on pages and other operations with URL addresses.
CURL Utility
Before proceeding to the description of how the curl linux command can be used, let’s take a look at the utility itself and its main options that we need. The utility syntax is very simple:
Use CURL to Download File
The most common task is downloading files. Download the file is very simple. To do this, simply transfer the file name or the html page to the utility in the parameters:
But here you will find one surprise, the entire contents of the file will be sent to the standard output. To write it to any file use:

Use CURL to Download Multiple Files
If necessary, one command can download several files:
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:
Authentication with CURL
If the server requires authentication of one of the common types, for example, HTTP Basic or FTP, then curl can very easily cope with this task. To specify authentication data, simply enter them with a colon in the -u option:
Using Proxy
If you need to use a proxy server to download files, then it is also very simple. It is enough to set the proxy server address in the -x option:
CURL’s Options
Now consider the main options:
-a, –append Append to target file when uploading (F/SFTP)
-E, –cert CERT[:PASSWD] Client certificate file and password (SSL)
-K, –config FILE Read config from FILE
-C, –continue-at OFFSET Resumed transfer OFFSET
-b, –cookie STRING/FILE Read cookies from STRING/FILE (H)
-c, –cookie-jar FILE Write cookies to FILE after operation (H)
-d, –data DATA HTTP POST data (H)
-D, –dump-header FILE Write the received headers to FILE
-f, –fail Fail silently (no output at all) on HTTP errors (H)
-F, –form CONTENT Specify HTTP multipart POST data (H)
-P, –ftp-port ADR Use PORT with given address instead of PASV (F)
-G, –get Send the -d data with a HTTP GET (H)
-g, –globoff Disable URL sequences and ranges using {} and []
-H, –header LINE Pass custom header LINE to server (H)
-I, –head Show document info only
-h, –help This help text
-0, –http1.0 Use HTTP 1.0 (H)
-i, –include Include protocol headers in the output (H/F)
-k, –insecure Allow connections to SSL sites without certs (H)
-4, –ipv4 Resolve name to IPv4 address
-6, –ipv6 Resolve name to IPv6 address
-j, –junk-session-cookies Ignore session cookies read from file (H)
-l, –list-only List only mode (F/POP3)
-L, –location Follow redirects (H)
-M, –manual Display the full manual
-m, –max-time SECONDS Maximum time allowed for the transfer
-n, –netrc Must read .netrc for user name and password

Conclusion
This article describes the basic commands for working with CURL. If suddenly you want to expand your knowledge of working with the utility, check the table above or type this command in Command Line:
In this article we looked at how to use curl, why we need this utility and its main features. Despite their similarity with wget, they are very different. The curl command is designed more to analyze and simulate various actions on the server, while wget is more suitable for downloading files and crawling sites.
What is cURL?
cURL is a command-line tool that lets you transfer data to/from a server using various protocols. In this case, the curl command will establish a communication to POST or GET data to/from Ubidots Server over HTTP and HTTPS.
