OS X: equivalent of Linux's wget
brew install wget
Homebrew is a package manager for OSX analogous to yum, apt-get, choco, emerge, etc. Be aware that you will also need to install Xcode and the Command Line Tools. Virtually anyone who uses the command line in OSX will want to install these things anyway.
If you can't or don't want to use homebrew, you could also:
Install wget manually:
curl -# "http://ftp.gnu.org/gnu/wget/wget-1.17.1.tar.xz" -o "wget.tar.xz"tar xf wget.tar.xzcd wget-1.17.1./configure --with-ssl=openssl -with-libssl-prefix=/usr/local/ssl && make -j8 && make installOr, use a bash alias:
function _wget() { curl "${1}" -o $(basename "${1}") ; };alias wget='_wget'
