Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

1. Take the download.sh file and put it into a directory where you want the files to be saved.
2. cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
3. Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

Out of the night that covers me, 
      Black as the pit from pole to pole, 
I thank whatever gods may be 
      For my unconquerable soul. 

In the fell clutch of circumstance 
      I have not winced nor cried aloud. 
Under the bludgeonings of chance 
      My head is bloody, but unbowed.
