Homebrew Wget
What does WGET Do?
Installing Wget: 1. On macOS Sierra. We need to install Wget to use it on our systems. Most Linux systems come with Wget pre-installed. However, for mac users, Wget installation is needed. The easiest way is to use Homebrew. Here are the steps to install it: Step 1: To install Homebrew open Terminal on your macOS and type the following command. — Using the macOS Terminal. To access the command line interface on your Mac, you’ll use the.
Once installed, the WGET command allows you to download files over the TCP/IP protocols: FTP, HTTP and HTTPS.
If you’re a Linux or Mac user, WGET is either already included in the package you’re running or it’s a trivial case of installing from whatever repository you prefer with a single command.
Unfortunately, it’s not quite that simple in Windows (although it’s still very easy!).
To run WGET you need to download, unzip and install manually.
Install WGET in Windows 10
Download the classic 32 bit version 1.14 here or, go to this Windows binaries collection at Eternally Bored here for the later versions and the faster 64 bit builds.
Here is the downloadable zip file for version 1.2 64 bit.
If you want to be able to run WGET from any directory inside the command terminal, you’ll need to learn about path variables in Windows to work out where to copy your new executable. If you follow these steps, you’ll be able to make WGET a command you can run from any directory in Command Prompt.
Run WGET from anywhere
Firstly, we need to determine where to copy WGET.exe.
After you’d downloaded wget.exe (or unpacked the associated distribution zip files) open a command terminal by typing “cmd” in the search menu:
We’re going to move wget.exe into a Windows directory that will allow WGET to be run from anywhere.
First, we need to find out which directory that should be. Type:
path
You should see something like this:
Thanks to the “Path” environment variable, we know that we need to copy wget.exe to the c:WindowsSystem32 folder location.
Go ahead and copy WGET.exe to the System32 directory and restart your Command Prompt.
Restart command terminal and test WGET
If you want to test WGET is working properly, restart your terminal and type:
wget -h
If you’ve copied the file to the right place, you’ll see a help file appear with all of the available commands.
So, you should see something like this:
Now it’s time to get started.
Get started with WGET
Seeing that we’ll be working in Command Prompt, let’s create a download directory just for WGET downloads.
To create a directory, we’ll use the command md (“make directory”).
Change to the c:/ prompt and type:
md wgetdown
Then, change to your new directory and type “dir” to see the (blank) contents.
Now, you’re ready to do some downloading.
Example commands
Once you’ve got WGET installed and you’ve created a new directory, all you have to do is learn some of the finer points of WGET arguments to make sure you get what you need.
Uninstall Wget Homebrew
The Gnu.org WGET manual is a particularly useful resource for those inclined to really learn the details.
If you want some quick commands though, read on. I’ve listed a set of instructions to WGET to recursively mirror your site, download all the images, CSS and JavaScript, localise all of the URLs (so the site works on your local machine), and save all the pages as a .html file.
To mirror your site execute this command:
wget -r https://www.yoursite.com
To mirror the site and localise all of the urls:
wget --convert-links -r https://www.yoursite.com
To make a full offline mirror of a site:
wget --mirror --convert-links --adjust-extension --page-requisites --no-parent https://www.yoursite.com
To mirror the site and save the files as .html:
wget --html-extension -r https://www.yoursite.com
To download all jpg images from a site:
wget -A '*.jpg' -r https://www.yoursite.com
Install Wget In Mac
For more filetype-specific operations, check out this useful thread on Stack.
Set a different user agent:
Some web servers are set up to deny WGET’s default user agent – for obvious, bandwidth saving reasons. You could try changing your user agent to get round this. For example, by pretending to be Googlebot:
wget --user-agent='Googlebot/2.1 (+https://www.googlebot.com/bot.html)' -r https://www.yoursite.com
Wget “spider” mode:
Wget can fetch pages without saving them which can be a useful feature in case you’re looking for broken links on a website. Remember to enable recursive mode, which allows wget to scan through the document and look for links to traverse.
wget --spider -r https://www.yoursite.com
You can also save this to a log file by adding this option:
wget --spider -r https://www.yoursite.com -o wget.log

How to install brew packages based on XCode, Ruby, Homebrew
- Install Homebrew
- Formulas
This tutorial provides a deep dive of Homebrew,a package manager for Mac OSX (MacOS)that’s like other package mangers for Linux:
| Distribution | Package Manager | Format | GUI tools |
|---|---|---|---|
| Darwin (macOS) | Homebrew | - | brew |
| Debian, Ubuntu | dpkg | .deb | APT (Advanced Packaging Tool) |
| RedHat, Fedora, openSUSE | RPM | .rpm | Yum, apt4rpm, up2date, urpmi, ZYpp, poldek |
| Slackware | tgz | - | - |
| Arch Linux, Frugalware, DeLi Linux | Pacman | - | - |
| Puppy Linux | PETget | - | - |
| Windows | Chocolatey | - | choco |
Mac Wget Homebrew
Step-by-step instructions are provided here to install Homebrew itselfand then install Homebrew packages based on the name of formulae specified for installationin a command such as:
brew install wget
DEFINITION: A formula provides instructions on how to install packages andtheir dependencies, such as where to find tar.gzip files for download.
Brew installs packages in its own Cellar directory (folder)and adds symlinks to the /usr/local folder.
Homebrew is the newest and most popular package utility on OSX.
Homebrew’s web page is at http://brew.sh
Alternatives to Homebrew
Preparations: XCode CLI
Make a full backup of your system right before following these instructions.
Open the App Store to install XCode, Apple’s IDE for developing Swift and Objective-C to run on iPhones and iPads.
PROTIP: Apple’s App Store only installs .app files. So programs invoked from the command line Terminal (such as gcc) need to be installed a different way.
To verify XCode CLI install:
This message means that it’s not installed:
Open a Terminal to install XCode CLI:
If XCode is not already installed, you are prompted to install it:
Installation is to folder: /Library/Developer/CommandLineTools/.
Homebrew requires OS X 10.5+ and the Xcode command line tools.
To download the Command Line Utilities, go to https://developer.apple.com/download/more/and look for your version of “Command Line Tools (macOS 10.14) for XCode 10”, one that doesn’t say “beta”.
Since the El Capitan version of Mac OSX, file permissions in /usr/local have changed,causing error messages such as:
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
So in a Terminal shell window at any folder:
sudo chown -R :staff /usr/local
Verify installation by getting the version of the GNU Compiler Collection:
gcc --version
You should see something like this (for Mojave):
Install Homebrew
Homebrew makes use of Ruby, which comes with macOS.
Install Homebrew if you haven’t already.
CAUTION: Don’t press Enter on the Terminal until the Download Software dialog reaches 100%.
Press the Enter key to the message:
Press RETURN to continue or any other key to abort. thenTo proceed, enter the root password, or type Ctrl+C to abort.
NOTE: The download is from

Install formula
Install the wget command-line utility by formula name (for example, wget):
brew install wget
This installs to folder /usr/local/bin/wget.

How many?
Get a count of kegs, how many files, and the disk space they take:
A sample response:
Where did it go?
List where .tar.gz “bottle” files are downloaded into from the internet:
DEFINITION: A “Bottle” is a pre-built binary Keg used for installation instead of building from source.It can be unpacked.
The response includes your user name, which enablesHomebrew to work without using sudo (elevation to root).
The equivalent of the above is:
List bottles downloaded:
Examples of responses:
List brew formulas installed:
ls /usr/local/Cellar
brew list
brew lsThe alternative commands above all do the same thing of the same folder,for example:
There is no response if no brew package has been installed.
See one level below one of the above folders for a specific formula,such as openssl:
It is usually a version number, such as:
DEFINITION: A “Keg” is the installation prefix of a formula, such as:
Packages
List brew package .rb (Ruby language) files installed:
The response is a long list.
List brew package folders:
brew search
The response is a long list.
Troubleshoot Homebrew
Homebrew Wget
Different ways to install weget.
The above is one of several ways to install the wget command-line utility.
One way is to install Apple’s Xcode.
Test wget operating:
cd ~/Downloads
wget http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gzVerify brew installation:
brew doctor
If you see this message at the top of messages returned:
The above may occur if curl and nodejs were installed without using homebrew.
Remove them before installing node and curl using Homebrew:
Create symlinks to installations performed manually in Cellar. This allows you to have the flexibility to install things on your own but still have those participate as dependencies in homebrew formulas.
First, see what exactly will be overwritten, without actually doing it:
The response is:
“Keg-only” refers to a formula installed only into the Cellar and not linked into /usr/local, which means most tools will not find it. This is to avoid conflicting with the system version of the same package.
Alternately, if aswcli is specified for dry-run, the response is:
brew link
NOTE: Homebrew installs to the Cellar it then symlinks some of the installation into /usr/local so that other programs can see what’s going on.
A symlink to the active version of a Keg is called an “opt prefix”.
List where a link goes:
ls -l $(which wget)
Prune symlinks
If you see this message:
A sample response:
List formula (package definitions):
brew edit $FORMULA
The above command brings you to your default text editor (vim or whatever is specified in the $EDITOR variable).
Type :q to quit out.
Upgrade brew formulas
List brew packages that are obsolete:
brew outdated
To stop a specific package from being updated/upgraded,pin it:
brew pin $FORMULA
$FORMULA is ???
To allow that formulae to update again, unpin it.
Download and update ALL software packages installed:
brew upgrade
To see which files would be removed as no longer needed:
brew cleanup -n
No response if there is nothing to clean. Otherwise, example:
To really remove all files no longer needed:
brew cleanup
A sample response:
Remove/Uninstalll
PROTIP: Before deleting, identify its dependencies. For example:
Two delete commands does the same: Additional flags: `–force` or `-f` forcibly removes all versions of that package. `–ignore-dependencies` ignore dependencies for the formula when uninstalling the designated package, which may cause other brews to no longer work correctly.## Tap #Brew tap adds repos not in the Homebrew master repofrom inside a larger package.https://github.com/Homebrew/brew/blob/master/docs/brew-tap.mdsays tap adds to the list of formulae that brew tracks, updates, and installs from.0.
