The command line tool wget lets you retrieve a group of files from FTP and HTTP protocols, it’s a very useful utility for web developers and powerusers to have around because it lets you do things like perform quick and dirty site backups and even mirror websites locally.
This approach is going to build and install wget in OS X from source, this means you’ll need Xcode and the Unix dev tools (free @ Mac App Store) installed, but it has the benefit of eliminating the need of a package manager like Homebrew or MacPorts.
Assuming you have Xcode and the command line tools installed, launch Terminal and enter the following commands:
First, use curl to download the latest wget source: curl -O http://ftp.gnu.org/gnu/wget/wget-1.13.4.tar.gz
Next we use tar to uncompress the files you just downloaded: tar -xzf wget-1.13.4.tar.gz
Use cd to change to the directory: cd wget-1.13.4
Configure with the appropriate –with-ssl flag to prevent a “GNUTLS not available” error: ./configure --with-ssl=openssl
Build the source: make
Install wget, it ends up in /usr/local/bin/: sudo make install
Confirm everything worked by running wget: wget --help
Clean up by removing wget source files when finished: cd .. && rm -rf wget*
You’re all set, enjoy wget in Mac OS X.
