Extracting the tarball

The dowloaded file is called linux_training.tar.gz and is a gzipped tarball containing the following directories:

TEXfiles
build
images

To extract these directories and the files they contain you will need the gzip and tar utilities. These come as standard on most UNIX and Linux systems. To untar the archive simply type the following in the directory where you downloaded the file.

gzip -dc linux_training.tar.gz | tar -xf -
