This script rips DVD/Blu-ray using makemkvcon. Use udev to invoke this script to auto-rip when disk is inserted. Some variables such as length of string to trim in order to get the title of movie may vary depending on your environment.

diskripper.sh

#!/bin/bash
{
  echo $(date)

  echo ">>>Disk found"
  echo ">>>Setting the title..."

  title=$(makemkvcon -r info)
  title=`echo "$title" | grep "DRV:0\+"`
  title=${title:53}
  len=${#title}-12
  title=${title:0:$len}

  if [[ -z $title ]]; then
    echo ">>>Couldn't set the title - No disk found"
    echo ">>>Exit->"
    exit;
  else
    echo ">>>Title set: $title"
    echo ">>>Starting ripping..."

    makemkvcon --minlength=4800 -r --decrypt --directio=true mkv disc:0 all /home/user/share > /dev/null

    mv "/home/user/raid/share/"*.mkv "/home/user/raid/share/"$title.mkv
    mv "/home/user/raid/share/"$title.mkv "/home/user/raid/share/Movies"

    eject
    echo ">>>title: $title.mkv created."

fi
} &>> "/home/user/autorip.log"

Have you considered TV shows where there are multiple titles?

You could use cut to pick field 6 from the output of makemkvcon -r info.

I personally like the pretty title that bdmt_eng.xml provides. I extract it with:

xmlstarlet select --text -N di="urn:BDA:bdmv;discinfo" --template --match '//di:name' --value-of . "${mountpoint}/BDMV/META/DL/bdmt_eng.xml"

Also, the output of makemkvcon will be a lot shorter if you don't include -r and you won't need > /dev/null. The command will run just fine without that option.
