Time to time I have to install RTL-SDR on a Linux Machine. There is a lot if rubish on internet about how to install RTL-SDR drivers. Here is a simple snipplet to install sdr drivers:
# apt-get update
# apt-get install -y libusb-1.0-0-dev pkg-config ca-certificates git-core cmake build-essential
# echo 'blacklist dvb_usb_rtl28xxu' > /etc/modprobe.d/raspi-blacklist.conf
# git clone git://git.osmocom.org/rtl-sdr.git
# mkdir rtl-sdr/build
# cd rtl-sdr/build
# cmake ../ -DINSTALL\_UDEV\_RULES=ON -DDETACH\_KERNEL\_DRIVER=ON
# make
# make install
# ldconfig
# rm -rf /tmp/rtl-sdr
