welcome back in this lesson we will introduce another command-line tool for downloading data called W gate we will walk through how to install and setup W get along with some basic usage W get derives its name from World Wide Web and get it is a GNU project native to the Linux system but is compatible across all operating systems it is another command-line tool that will help you download files via HTTP and FTP compared to curl W get is more multi-purpose it can download a single file an entire folder or even a web page most importantly it makes multiple file downloads possible recursively a site from using man another way to check if W get has been installed correctly is by using which W get this will return the location of where W get is installed for example and the local user bin every W get has not been installed there will simply be no output the official documentation and source code for W get is listed but unless you are comfortable compiling from the source code here are some easier alternatives for Linux users it is likely W get is already installed free if not run sudo apt-get install W get on the command line for Mac users use homebrew by running brew install W get on the command line for Windows users this will not be a command line install rather visit the link listed on the slide to download as part of the GNU win32 package once installation is complete use the man command to print the W get menu remember to press ENTER to scroll and to press Q to exit the basic syntax for W get has a similar structure to curl W get option Flags URL the you are is also required for the W get command to run successfully W get supports a large number of protocol calls for data stored on servers for a full list of the options available refer to W get - - help here are some option flags unique TW get - lowercase B allows your download to run in the background - lowercase Q turns off the W get output which saves some disk space - lowercase C is useful to finish up a previously broken download weather by W get or another program finally you can link all the option flags together like this W get - bqc followed by the file location running this command on this hypothetical file location will generate the output continuing in background PID 1 2 3 4 5 the PID is a unique process ID assigned to this particular data download job for your reference in case you need to cancel the process in this lesson we learned another way to download files

Welcome back! In this lesson, we will introduce another command line tool for downloading data, called Wget. We will walk through how to install and set up Wget along with some basic usage.
Wget derives its name from World Wide Web and get.
It is a GNU project native to the Linux system, but is compatible across all operating systems.
It is another command line tool that will help you download files via HTTP and FTP.
Compared to curl, Wget is more multi-purpose. It can download a single file, an entire folder, or even a webpage. Most importantly, it makes multiple file downloads possible recursively.
Aside from using man, another way to check if Wget has been installed correctly, is by using which Wget.
This will return the location of where Wget is installed. For example, in the local user bin:
If Wget has not been installed, there will simply be no output.
The official documentation and source code for Wget is listed, but unless you are comfortable compiling from the source code, here are some easier alternatives.
For Linux users, it's likely Wget is already installed for you. If not, run sudo apt get install wget on the command line.
For Mac users, use homebrew by running brew install wget on the command line.
For Windows users, this will not be a command line install. Rather, visit the link listed on the slide to download as part of the gnuwin32 package.
Once installation is complete, use the man command to print the Wget manual.
Remember to press Enter to scroll and to press q to exit.
The basic syntax for Wget has a similar structure to curl:
Wget, option flags, URL
The URL is also required for the Wget command to run successfully.
Wget supports a large number of protocol calls for data stored on serv
