Unrar and cleanup script - UPDATE 2013.05.24

Post by killemov » Sat Jul 31, 2010 5:21 pm

Hello,

I have implemented this script for Debian to run from transmission-daemon after a download has finished.

regards,

K.

Dependencies:
  • Debian (bash compatibility, system configuration)
  • unrar
  • sleep
  • transmission-remote
To make the script work you have to add/change these lines in a configuration file named "settings.json" (usually /etc/transmission-daemon/settings.json) while transmission-daemon is not running.

Code: Select all

    "script-torrent-done-enabled": true, 
    "script-torrent-done-filename": "/var/lib/scripts/posttorrent.sh", 
The posttorrent.sh script:

Code: Select all

#! /bin/bash
# posttorrent.sh by Killemov
{
  # Log file, file where we tell what events have been processed.
  LOG_FILE=/var/log/posttorrent.log
  # Username for transmission remote.
  TR_USERNAME="username"
  # Password for transmission remote.
  TR_PASSWORD="password"
  # Get current time.
  NOW=$(date +%Y-%m-%d\ %H:%M:%S)
  # Source directory, should not be changed.
  SRC_DIR="${TR_TORRENT_DIR}/${TR_TORRENT_NAME}"
  # Directory to store the un-compressed files in..
  DEST_DIR="${TR_TORRENT_DIR}/${TR_TORRENT_NAME}/"
  # This parameter string could be passed from Transmission in the future.
  TR_TORRENT_PARAMETER="EXTRACT SLEEP1h"

  if [ -e "$SRC_DIR/keep" ]; then
    TR_TORRENT_PARAMETER="$TR_TORRENT_PARAMETER KEEP"
  fi

  if [ -e "$SRC_DIR/exit" ]; then
    TR_TORRENT_PARAMETER="EXIT"
  fi

  # Actual processing starts here.
  if [[ "$TR_TORRENT_PARAMETER" =~ "EXIT" ]]; then
    echo $NOW "Exiting $TR_TORRENT_NAME" >> $LOG_FILE
    exit 0
  fi

  if [[ "$TR_TORRENT_PARAMETER" =~ "EXTRACT" ]]; then
    cd $TR_TORRENT_DIR
    if [ -d "$SRC_DIR" ]; then
      IFS=$'\n'
      unset RAR_FILES i
      for RAR_FILE in $( find "$SRC_DIR" -type f -iname "*.rar" ); do
        if [[ $RAR_FILE =~ .*part.*.rar ]]; then
          if [[ $RAR_FILE =~ .*part0*1.rar ]]; then
            RAR_FILES[i++]=$RAR_FILE
          fi
        else
          RAR_FILES[i++]=$RAR_FILE
        fi
      done
      unset IFS

      if [ ${#RAR_FILES} -gt 0 ]; then
        for RAR_FILE in "${RAR_FILES[@]}"; do
          unrar x -inul "$RAR_FILE" "$DEST_DIR"
          if [ $? -gt 0 ]; then
            echo $NOW "Error unrarring $TR_TORRENT_NAME" >> $LOG_FILE
            transmission-remote -n $TR_USERNAME:$TR_PASSWORD -t $TR_TORRENT_HASH --verify --start
            exit 0
          fi
        done
        if [[ ! "$TR_TORRENT_PARAMETER" =~ "KEEP" ]]; then
          SLEEP=$(expr match "$TR_TORRENT_PARAMETER" '.*SLEEP\([0-9a-zA-Z]*\)')
          if [ ${#SLEEP} -gt 0 ]; then
            sleep $SLEEP
          fi
          transmission-remote -n $TR_USERNAME:$TR_PASSWORD -t $TR_TORRENT_HASH --remove-and-delete
        fi
        echo $NOW "Unrarred $TR_TORRENT_NAME" >> $LOG_FILE
      fi
    fi
  fi
} &
Control files:
  • "exit" - If a file named exit is present in the root of the torrents' folder then no processing is done at all.
  • "keep" - If a file named keep is present in the root of the torrents' folder then no files will be removed.

I am trying to use this script but had no luck. Anyone made it work ?

I am using Transmission 2.04 on a Synology 110j NAS.

Do you have the stock firmware on it? Then it probably isn't equipped to run even the most basic commands in the script. Try running unrar from the shell for instance.

Cool, is it possible to choose wich dir it will unrar to ? and if I don't wan't it to keep the torrent seeded I just comment the following line right?

transmission-remote -n name:password -t$TR_TORRENT_ID --remove-and-delete &

Yes and Yes.

See the options for unrar on how to unrar to a FIXED directory. All your content from rarred torrents will end up in a single directory.

then

Well I have the same problem. In telnet I can use the unrar command but de script gave some errors. Is there somebody who can tell how to get this script working on a synology disk station? I'm kinda linux n00b....

If it gives you any error messages then please post them since otherwise we don't know where to start helping you.

Personally I would use links instead of copying it, saves lots of space. Although if you are transferring it to another computer then of course copy is better.

Maybe something like this would do. NOTE: Only done minimal testing to get any syntax errors out.

First you'll have to change the DEST_DIR-variable to your preferred dir. You can add "$DEST_DIR" to the unrar line if you also want your unrars to end up there.
Second, choosing if copying or linking. Remove the # in front of the cp-line at the bottom if copying or the linker-line if linking.

Code: Select all

#!/bin/sh
# posttorrent.sh by Killemov

DEST_DIR="/some/other/dir"

function linker() {
  if [ ! -d "$DEST_DIR/$1" ]; then mkdir "$DEST_DIR/$1"; fi
  cd "$1"
  for F in *; do
    if [ -d "$F" ]; then linker "$1/$F"; fi
    ln -s "$TR_TORRENT_DIR/$1/$F" "$DEST_DIR/$1"
  done
}

cd $TR_TORRENT_DIR
if [ -d "$TR_TORRENT_NAME" ]
then
  if ls "$TR_TORRENT_NAME"/*.rar > /dev/null 2>&1
  then
    find "$TR_TORRENT_NAME" -iname "*.rar" | while read file
    do
      unrar x -inul "$file"
    done
    transmission-remote -n name:password -t$TR_TORRENT_ID --remove-and-delete &
    echo "Unrarred $TR_TORRENT_NAME" >> /var/log/posttorrent.log
  else
    # cp -r "$TR_TORRENT_NAME" "$DEST_DIR"
    # linker "$TR_TORRENT_NAME"
  fi
fi
If you want it to also work on single-file torrents then add this between the two fi-files:

Code: Select all

else
  # cp "$TR_TORRENT_NAME" "$DEST_DIR"
  # ln -s "$TR_TORRENT_NAME" "$DEST_DIR"
And same here, cp-line for copy or ln-line for linking.


If linking then I recommend getting the symlinks program which will make cleaning up broken links (after removing the original) much easier.

Is it possible to extend this script to support *zip file format as well?

Of course it is:

Code: Select all

#!/bin/sh
# posttorrent.sh by Killemov

DEST_DIR="/some/other/dir"

function linker() {
  if [ ! -d "$DEST_DIR/$1" ]; then mkdir "$DEST_DIR/$1"; fi
  cd "$1"
  for F in *; do
    if [ -d "$F" ]; then linker "$1/$F"; fi
    ln -s "$TR_TORRENT_DIR/$1/$F" "$DEST_DIR/$1"
  done
}

cd $TR_TORRENT_DIR
if [ -d "$TR_TORRENT_NAME" ]
then
  if ls "$TR_TORRENT_NAME"/*.rar > /dev/null 2>&1
  then
    find "$TR_TORRENT_NAME" -iname "*.rar" | while read file
    do
      unrar x -inul "$file"
    done
    transmission-remote -n name:password -t$TR_TORRENT_ID --remove-and-delete &
    echo "Unrarred $TR_TORRENT_NAME" >> /var/log/posttorrent.log
  elif ls "$TR_TORRENT_NAME"/*.zip > /dev/null 2>&1
  then
    find "$TR_TORRENT_NAME" -iname "*.zip" | while read file
    do
      unzip "$file"
    done
    transmission-remote -n name:password -t$TR_TORRENT_ID --remove-and-delete &
    echo "Unzipped $TR_TORRENT_NAME" >> /var/log/posttorrent.log
  else

    # cp -r "$TR_TORRENT_NAME" "$DEST_DIR"
    # linker "$TR_TORRENT_NAME"
  fi
fi
