Question: I typically use wget to download files. On some systems, wget is not installed and only curl is available. Can you explain me with a simple example on how I can download a remote file using curl? Are there any difference between curl and wget?
Answer: On a high-level, both wget and curl are command line utilities that do the same thing.
They both can be used to download files using FTP and HTTP(s).
You can also send HTTP POST request using curl and wget
However curl provides APIs that can be used by programmers inside their own code. curl uses libcurl which is a cross-platform library.
wget is just a command-line tool without any APIs.
Curl also supports lot more protocols that wget doesn’t support. For example: SCP, SFTP, TFTP, TELNET, LDAP(S), FILE, POP3, IMAP, SMTP, RTMP and RTSP.
There is a major advantage of using wget. wget supports recursive download, while curl doesn’t.

Step 4: Use the contents of the certreq.csr file to generate a certificate from your certificate provider. Request a SHA-1 certificate (SHA-2 is untested but will likely work). If using DigiCert, download the resulting certificate as Other format 'a.p7b bundle of all the certs in a.p7b file'.

The tool will now download and install the latest version of Groovy and place it on your path ready for use.

Curl Examples
Option -O (upper-case O) is important. Without this, curl will start dumping the downloaded file on the stdout. Using -O, it downloads the files in the same name as the remote server. In the above example, we are downloading strx25-0.9.2.1.tar.bz2, so the downloaded file will also be the same name.
% – The total % of the download that was completed as of now. When it gets to 100% the download is completed. In the above example, it has downloaded only 28% of the file.
Total – The total size of the file
Received – The total size of the file that was has been downloaded so far. In the above example, it has downloaded 1085k so far (out of 3762k total)
Xferd – This will be used when you upload some files to the remote server. During upload, this will indicate the total size of the file that has been uploaded so far. Since we are downloading a file, in this example, this is 0.
Average Speed Dload – This indicates the average download speed.
AVerage Speed Upload – While uploading a file, this will indicate the average upload speed
Time Total – This indicates the total time it will take to download (or upload) the whole file based on the current download (or upload) speed. In this example, it will take approximately a total of 52 seconds to download this file.
Time Spend – The time curl has spent so far downloading (or uploading) the file. In this example, it has spent 15 seconds so far.
Time Left – This is caculated based on “Time Total” – “Time Spent”.
Current Speed – This indicates the current download/upload speed. Compare this with Average Spped Dload/UPload to see how fast or slow your system is downloading currently.
If you want to download the file and store it in a different name than the name of the file in the remote server, use -o (lower-case o) as shown below. This is helpful when the remote URL doesn’t contain the file name in the url as shown in the example below.
In the above example, there is no file name in the remote URL, it just calls a php script that passes some parameter to it. However, the file will be downloaded and saved as taglist.zip on your local system. Instead of -o, you an also specify, “–output”.
