wget is a strong command line software for downloading URL-specified sources. It was designed to work excellently even when connections are poor. Its distinctive function, in comparison with curl which ships with macOS, for instance, is that it’s non-interactive so it could possibly run within the background.
There are 2 methods to put in wget: through Xcode or through Homebrew and I’ll cowl each strategies since not everybody makes use of Xcode or Homebrew.
Putting in Wget through Xcode
Putting in wget on Mac through Xcode requires you to construct the device from supply and the steps are the identical on all a Mac variations:
First, set up Xcode through iTunes after which set up Xcode command line instruments with the command:
# xcode-select –install
Obtain wget supply code utilizing curl:
# cd ~/Downloads
# curl -O https://ftp.gnu.org/gnu/wget/wget-1.19.5.tar.gz
Extract and navigate into the folder and run the configure command:
# tar -zxvf wget-1.19.5.tar.gz
# cd wget-1.19.5/
Make and take a look at wget:
# make set up
# wget http://ftp.gnu.org/gnu/wget/wget-1.19.5.tar.gz
In case you get an error if you run the configure command then run it with an SSL flag like so:
# ./configure –with-ssl=openssl
Bear in mind to delete the now-unnecessary information after the set up is full.
Putting in Wget through Homebrew
Homebrew is a package deal supervisor for OS X that makes putting in and managing purposes lots simpler for Mac customers.
There are alternate options like Fink and MacPorts however I want utilizing Homebrew. Don’t fear in the event you don’t have it put in, I’ve received you coated:
Set up Homebrew utilizing the next command, it’ll additionally set up Xcode’s command line instruments in the event that they aren’t already put in:
# /usr/bin/ruby -e “$(curl -fsSL https://uncooked.githubusercontent.com/Homebrew/set up/grasp/set up)”
Subsequent, set up wget command-line obtain consumer.
# brew set up wget
Methods to Use Wget on Mac
So long as a file or listing’s URL is publicly accessible, you may obtain it and information will be downloaded singly or recursively when downloading directories.
Downloading a single file
# wget -X path/to/native.copy http://instance.com/url/to/obtain.html
The syntax is straightforward. the wget command, -X to point the file path (until you need to save the downloaded content material to your present working listing), and the general public hyperlink.
Downloading a listing
# wget -e robots=off -r -np https://www.w3.org/Historical past/19921103-hypertext/hypertext/
The -e robots=off flag tells wget to disregard restrictions within the robots.txt file which is nice as a result of it prevents abridged downloads. -r (or –recursive) and -np (or –no-parent) tells wget to observe hyperlinks throughout the listing that you just’ve specified. Voila!
Whereas that’s all that it’s essential to know to make use of wget for downloading information, there are numerous different instructions that’ll allow you to manage its utilization and you’ll entry them inside your terminal in wget’s man web page or on-line.
