Im trying to install Calibre e-book manager on my computer, i'm a newbie to linux and i dont know where the "installation directory" is....Here are the commands that they have in order to install it...
sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main()"
"One can also avoid having the installer script ask for the installation directory by specifying it in the install command itself, as shown below:"
sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main(install_dir='/path/to/your/library')"
