OSX installation

To set up your own computer for today’s session, follow these instructions. Copying and pasting the given code may be the easiest way to make sure everything works.

1. Open a Terminal Applications -> Utilities -> Terminal.
2. If you don’t have homebrew installed, type the following to your terminal. If you do have homebrew installed, please skip to the next step

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

3. Install GNU sed and wget by entering the following commands in your terminal

   brew install gnu-sed --default-names
   brew install wget
   

4. Add the paths of the recently installed sed and wget into your PATH

   echo "export PATH=\${PATH}:/usr/local/Cellar/gnu-sed/4.4/bin:/usr/local/Cellar/wget/1.19.1_1/bin" >> ~/.bash_profile
   

After completing the above steps, close the terminal then open it again. To test if these installations have been successful enter the following:

sed --version

This should give you the version of GNU sed. If you see an error, the installation hasn’t worked, and you should call an instructor over.

If the first test was successful, enter the following

wget --version

Again, this should give you the correct version of wget. If you see an error, the installation hasn’t worked, and you should call an instructor over.
