The Ultimate Guide to Downloading Go with cURL
The tarball download works fine with wget command. I tried reading more about the difference between the two and feel that the curl should have worked. I never had issues with using curl before when downloading archives for e.g., linux source tarball. I am really not sure if the issue is with the curl or the golang server. Any explanation would be helpful.
Since its release, Go has become highly popular among developers and is used for various applications ranging from cloud or server-side applications, to artificial intelligence and robotics. This tutorial outlines how to download and install the latest version of Go (currently version 1.16.7) on an Ubuntu 20.04 server, build the famous Hello, World! application, and make your Go code into an executable binary for future use.

Then use curl to retrieve the tarball, making sure to replace the highlighted URL with the one you just copied. The -O flag ensures that this outputs to a file, and the L flag instructs HTTPS redirects, since this link was taken from the Go website and will redirect here before the file downloads:
The curl tool lets us fetch a given URL from the command-line. Sometimes we want to save a web file to our own computer. Other times we might pipe it directly into another program. Either way, curl has us covered.
Besides the display of a progress indicator (which I explain below), you don't have much indication of what curl actually downloaded. So let's confirm that a file named my.file was actually downloaded.
In the example of curl, the author apparently believes that it's important to tell the user the progress of the download. For a very small file, that status display is not terribly helpful. Let's try it with a bigger file (this is the baby names file from the Social Security Administration) to see how the progress indicator animates:

So those are the basics for the curl command. There are many, many more options, but for now, we know how to use curl to do something that is actually quite powerful: fetch a file, anywhere on the Internet, from the simple confines of our command-line.
But what if we wanted to send the contents of a web file to another program? Maybe to wc, which is used to count words and lines? Then we can use the powerful Unix feature of pipes. In this example, I'm using curl's silent option so that only the output of wc (and not the progress indicator) is seen. Also, I'm using the -l option for wc to just get the number of lines in the HTML for example.com:
As of Go 1.13, the go command by default downloads and authenticates modules using the Go module mirror and Go checksum database run by Google. See for privacy information about these services and the go command documentation for configuration details including how to disable the use of these servers or use different ones.
To change both the download directory and location of the configuration file, set the WORKSPACE environment variable toany user-writable directory. This approach is particularly useful if you have an isolated SnowSQL environment for each process.
In addition, you can separate the download directory from the configuration file by setting the SNOWSQL_DOWNLOAD_DIR environment variable so thatmultiple SnowSQL processes can share the binaries. For example:
If you want to download the installer from a script or a terminal window (e.g. by using curl, rather than your web browser),you can download the installers directly from the Snowflake Client Repository. For increased flexibility, Snowflakeprovides both Amazon Web Services (AWS) and Azure endpoints for the repository. Accounts hosted on any supported cloud platformcan download the installer from either endpoint.
When you install a new major or minor version, SnowSQL does not upgrade itself immediately. Rather, you must log into your Snowflake account using SnowSQL and remain connected for a sufficient period of time for the auto-upgrade feature to upgrade the client to the latest release. To verify the SnowSQL version that currently starts when you run the client, use the -v option without a value:
You can change both the download directory and location of the configuration file by setting the WORKSPACE environment variable to any user-writabledirectory. This is particularly useful if you have an isolated SnowSQL environment for each process.
Homebrew Cask is a popular extension of Homebrew used for package distribution, installation, andmaintenance. There is no separate SnowSQL installer to download. If Homebrew Cask is installed on your macOS platform, you can install Snowflake directly.
A change in the major version indicates dramatic improvements in the underlying Snowflake service. A new major version breaks backwardcompatibility. You will need to download and install the latest SnowSQL version from the web interface.
A change in the minor version indicates improvements to support forward compatibility in either SnowSQL or the underlying Snowflakeservice. A new minor version does not break backward compatibility, but we strongly recommend that you download and install the latest SnowSQL versionfrom the web interface.
If a minor version is released, the functionality in your current version should continue to work, but any newly-released bug fixes and features willnot be available via the auto-upgrade feature. Therefore, we strongly recommended that you download and install the latest SnowSQL versionif the minor version is increased.
Make sure you have git and Go installed.Go version 1.17 or newer is required, latest release is recommended.You can get it from your package manager, or download it fromgolang.org/dl. Then you can run the following:
This assumes you have a GCC compatible C compiler (GCC or Clang) in your PATH,as it uses cgo. But on Windows, thecgofuse library that the cmountimplementation is based on, also supports buildingwithout cgo, i.e. by settingenvironment variable CGO_ENABLED to value 0 (static linking). This is how theofficial Windows release of rclone is being built, starting with version 1.59.It is still possible to build with cgo on Windows as well, by using the MinGWport of GCC, e.g. by installing it in a MSYS2distribution (make sure you install it in the classic mingw64 subsystem, theucrt64 version is not compatible).
Another alternative is to download the source, build and install rclone in oneoperation, as a regular Go package. The source will be stored it in the Gomodule cache, and the resulting executable will be in your GOPATH bin folder($(go env GOPATH)/bin, which corresponds to /go/bin/rclone by default).
As mentioned above, rclone is singleexecutable (rclone, or rclone.exe on Windows) that you can download as azip archive and extract into a location of your choosing. When executing differentcommands, it may create files in different locations, such as a configuration fileand various temporary files. By default the locations for these are according toyour operating system, e.g. configuration file in your user profile directory andtemporary files in the standard temporary directory, but you can customize all ofthem, e.g. to make a completely self-contained, portable installation.
There are many HTTP/HTTPS links that require certain headers in order to work. So this will result in a working response from a web browser but not a working response in a backend web request like curl.
It lets you interact with remote systems by making requests to those systems and retrieving and displaying their responses to you. This can be files, images, etc. but it can also be an API call. curl supports over 20 protocols, including HTTP, HTTPS, SCP, SFTP, and FTP. And arguably, due to its superior handling of Linux pipes, curl can be more easily integrated with other commands and scripts.
