I learned that many of (La)TeX book examples are stored in
However, the directory with examples from the book LaTeX Companion 2nd ed does not provide the feature to download files in one zip file.
In this case, how to download all the files in the CTAN example directory?
Googling to find this site (https://stackoverflow.com/questions/23446635/how-to-download-http-directory-with-all-files-and-sub-directories-as-they-appear#) to use wget, but with this command, I could not download any file.
wget -r -np -nH --cut-dirs=3 -R index.html http://ctan.org/tex-archive/info/examples/LaTeX_Companion_2ed/
