[resolved] Move folder based on tag in nfo file

Hi,

I'm a full on OMV convert. From using a Win7 PC with some external storage the NAS world looked scary as hell. OMV is making the transition amazingly smooth. I've put in about 20+ hours of config so far and got things tweaked satisfactorily for most of the popular services, but I've run up against something I could do with some help on.

I like to organise my movies by UK age certification as follows:

/video
->/movies
->/u
->/pg
->/12
->/15
->/18

e.g. /video/movies/18/Expendables 2/movie.avi, movie.nfo, etc

This method allows simple access control levels for my kids and their XBMC libraries.
Couchpotato post-processing gives me perfect folder and file naming along with an XBMC compatible nfo file filled with IMDB data including <certification> tag.
Currently CouchPotato dumps the processed folder into /video/movies and I manually sort into the correct rating folder. What would completely automate this process is a perl or python script (along with a cron job) that watches for new movies turning up (perhaps a new folder like /video/movies/couchpotatodrop/), parses the nfo file for the certification value and then moves the movie folder to the appropriate rating folder.

Sadly I don't know Perl or Python and while my PHP experience tells me this isn't a hugely complex script it is still beyond me. Is there any Perl or Python guru on the board who would write a little script to do this job?

nfo file can be named "movie.nfo" or <folder name>/nfo [e.g. Expendables 2 (2012).nfo] soetimes with both files being present.

IMDB certification tag values can be:
"UK:18", "UK:15", "UK:12A", "UK:PG", "UK:U"

Some nfo files have certification data for lots of countires but the UK rating is always in the format above.

Any takers?

I know PHP so I've started cobbling together bits of Python from around the web.

Below is my progress so far but I'm coming up against my rough and ready abilities so getting stuck.

I'm pretty sure my syntax is all to shite and the pyinotify stuff, while very neat and powerful, just looks like Hieroglyphics to me.

Any help appreciated.

#!/usr/bin/python
import fnmatch, os, shutil, xml.sax
#detect new folder(target) in watch folder
# [pyinotify snippet to go here]


#enter that folder
os.chdir(target)


#find movie.nfo or target.nfo = file_name
#if the file doesn't exist pull the data ourselves from IMDB.  :(
if file in os.listdir('.'):
    if fnmatch.fnmatch(file, 'movie\.nfo'):
        file_name = movie.nfo;
elseif file in os.listdir('.'):
    if fnmatch.fnmatch(file, target.'\.nfo'):
        file_name = target.'\.nfo';
else:
    print('No matching nfo file found.'); 


#parse through movie.nfo and pull the certification value
class MovieHandler( xml.sax.ContentHandler ):
   def __init__(self):
      self.CurrentData = ""
      self.certification = ""


   # Call when an element starts
   def startElement(self, tag, attributes):
      self.CurrentData = tag
      if tag == "movie":
         # print "*****Movie*****"
         title = attributes["title"]
         # print "Title:", title


   # Call when an elements ends
   def endElement(self, tag):
      if self.CurrentData == "certification":
         #print "Certification:", self.certification
         xml_certification = self.certification
      self.CurrentData = ""


   # Call when a character is read
   def characters(self, content):
      if self.CurrentData == "certification":
         self.certification = content

if ( __name__ == "__main__"):

   # create an XMLReader
   parser = xml.sax.make_parser()
   # turn off namepsaces
   parser.setFeature(xml.sax.handler.feature_namespaces, 0)


   # override the default ContextHandler
   Handler = MovieHandler()
   parser.setContentHandler( Handler )

   parser.parse(file_name)


#pattern match the certification string for "UK:"
#pull the two characters after the colon
ukposition = certification.find('UK:')
rating = certification[ukposition:2]


#close nfo file and return to watch folder
fileObject.close()
os.chdir("../")


#move new folder to correct movies sub folder
if rating == 'U': 
  shutil.move(target, 'u/')
elseif rating == 'PG': 
  shutil.move(target, 'pg/')
elseif rating == '12A': 
  shutil.move(target, '12/')
elseif rating == '15': 
  shutil.move(target, '15/')
elseif rating == '18': 
  shutil.move(target, '18/')
else:
  #handle an error
  print('Rating value ='.rating.' for movie '.target.'\. Does not match certification folder');

Thanks for the help. Really is appreciated.

I don't know bash scripting syntax at all as yet. I can make out the logic of what you've written though. I'll learn some bash scripting and have another crack with this instead of Python.

Cheers.

This is perfect. Thank you so much. I've set it up as a cron job and will throw some folders at it over the weekend to see how it gets on.

Thanks again.

Hi,

Script isn't working for me I'm afraid. Here is the relevant folder structure:

/videos/movieshifter.sh
/videos/moviedump/Movie To Shift (2011)/Movie To Shift.avi
/videos/moviedump/Movie To Shift (2011)/Movie To Shift.nfo
/videos/moviedump/Movie To Shift (2011)/Movie To Shift.srt
/videos/moviedump/Movie To Shift (2011)/Movie To Shift.tbn
/videos/moviedump/Movie To Shift (2011)/folder.jpg
/videos/movies/u/
/videos/movies/pg
/videos/movies/12
/videos/movies/15
/videos/movies/18

movieshifter.sh:

#!/bin/bash


# Folder to search in
FOLDER="moviedump"


# Folders to place in
FOLDER_U="movies/u"
FOLDER_PG="movies/pg"
FOLDER_12="movies/12"
FOLDER_15="movies/15"
FOLDER_18="movies/18"


for D in "$(find $FOLDER -type d)"
do
  if grep -s "UK:18" $D/*.nfo
  then
    mv $D $FOLDER_18
    echo "moving $D to $FOLDER_18"
  elif grep -s "UK:15" $D/*.nfo
  then
    mv $D $FOLDER_15
    echo "moving $D to $FOLDER_15"
  elif grep -s "UK:12" $D/*.nfo
  then
    mv $D $FOLDER_12
    echo "moving $D to $FOLDER_12"
  elif grep -s "UK:PG" $D/*.nfo
  then
    mv $D $FOLDER_PG
    echo "moving $D to $FOLDER_PG"
  elif grep -s "UK:U" $D/*.nfo
  then
    mv $D $FOLDER_U
    echo "moving $D to $FOLDER_U"
  else
    echo "no rating found, skipping file"
  fi
done

I've put the find condition in quotes as the script was not handling folder names with spaces. It treated each word as a folder to search.

My output is always "no rating found, skipping file".
If I echo out $D I get "moviedump moviedump/Movie To Shift (2011)".
If I change grep to recursive then it finds the string "<certification>UK:12</certification>" correctly but nothing gets moved.

Still tinkering.

I've tried running that. Added in full paths but still no luck.

I've dropped the "-s" option form grep and that outputs "/media/unique-storage-string/video/moviedump/Name Of Folder (2011)/*.nfo: no such file or directory" but I am 100% sure the file it's looking for exists. I am running the script from /scripts at the OS root.

If I navigate to the moviedump folder via CLI and run (as root):

grep "UK:12" "Name Of Folder (2011)"/*.nfo

I get the correct output of <certification>UK:12</certification>. It looks like grep in the script is not using the wildcard for some reason.

Here you go Solo0815:

find: warning: Unix filenames usually don't contain slashes (though pathnames do).  That means that '-name `/media/unqiue-storage-identifier/video/moviedump/*/*.nfo'' will probably evaluate to false all the time on this system.  You might find the '-wholename' test more useful, or perhaps '-samefile'.  Alternatively, if you are using GNU grep, you could use 'find ... -print0 | grep -FzZ `/media/bb09e796-5566-4eb2-8fc1-043a156233c4/video/moviedump/*/*.nfo''.
Working on '' --- Folder = ''

That's it!
Absolutely perfect.
Thank you so much for this ryecoaaron and Solo0815. My media server is now completely automated and I can be sure my kids are only viewing age appropriate movies.
