Custom Post Processing Scripts

If you’re looking to trigger a custom script in your download client to tell Radarr when to update, you can find more details here. Scripts are added to Radarr via the Connect Settings page.

Overview

Radarr can execute a custom script when new movies are imported or a movie is renamed and depending on which action occurred, the parameters will be different. They are passed to the script through environment variables which allows for more flexibility in what is sent to the script and in no particular order.

LINUX / UNIX Scripts

Remember to always add a shebang and make your scripts executable with chmod.

Sample bash script to echo environmental variables

PHP

The information from Radarr will not be added to <math display="inline">_ENV as one might expect but should be included in the [</math>_SERVER variable](https://secure.php.net/manual/en/reserved.variables.server.php). A sample script to use this information to convert a file can be found here. #### PowerShell #### Sample script using the Radarr environment variables to create EDL files for all episodes is here.

Sample script to have Plex scan destination folder only and “analyze deeply” the file. PSQLite needed to query the plex DB. Adjust folder locations to match your setup.

# This script will add the movie to plex and scan the destination folder (it will not scan the entire library)
# C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe\PowerShell.exe -ExecutionPolicy Bypass "C:\Users\Server\Desktop\radarrcustom.ps1"

$movie_path = $env:radarr_movie_path
#PSQlite location
Import-Module C:\Users\Server\Desktop\scripts\PSSQLite
#set file locations
$logfile = "C:\Users\Server\Desktop\radarrimport.txt"
$database = "C:\Users\Server\AppData\Local\Plex Media Server\Plug-in Support\Databases\com.plexapp.plugins.library.db"
$plexscanner = "C:\Program Files (x86)\Plex\Plex Media Server\Plex Media Scanner.exe"
#set your plex library ID
$libraryid = 0
#If you have multiple root folders and library IDs you can set them like so
#If ($movie_path -like '*Movies Release\*' ) { $libraryid = 19 } 

#Scan the movie folder
& "$plexscanner" --scan --refresh --section $libraryid --directory $movie_path
write-output """$plexscanner"" --scan --refresh --section $libraryid --directory $movie_path" | add-content $logfile

sleep 20

#Query the plex db for the item ID
$likemoviepath = $movie_path + "%"
$query = "SELECT mi.metadata_item_id FROM media_parts mp LEFT JOIN media_items mi on mp.media_item_id=mi.id WHERE mp.file LIKE '$likemoviepath'"
$itemid = Invoke-SqliteQuery -Query $query -DataSource $database
$itemid = $itemid.metadata_item_id

#Analyze the ItemID
& "$plexscanner" --analyze --item $itemid
write-output """$plexscanner"" --analyze --item $itemid" | add-content $logfile

sleep 20

#Analyze deeply the item ID
& "$plexscanner" --analyze-deeply --item $itemid
write-output """$plexscanner"" --analyze-deeply --item $itemid" | add-content $logfile

Reverse Symlinking

When using private trackers, it is imperative to continue seeding. By using this script on Download and on Upgrade moves the media to your root movie folder as set in Radarr, and will create a symlink in the original download location so you can continue to seed.

Symlinking is preferable over hardlinking in most cases as the root movie folder can be on a seperate drive or nfs mount, where hardlinks are impossible.

#!/bin/bash

PERMPATH="$radarr_moviefile_path"
LINKPATH="$radarr_moviefile_sourcepath"

if [[ -f "$LINKPATH" ]]; then
    sleep 1
else
    exit 1
fi

ORIGFILESIZE=$(stat -c%s "$LINKPATH")
PERMFILESIZE=$(stat -c%s "$PERMPATH")

sleep 30

while [[ $PERMFILESIZE != $ORIGFILESIZE ]]; do
    sleep 60
    PERMFILESIZE=$(stat -c%s "$PERMPATH")
done

if [[ $PERMFILESIZE == $ORIGFILESIZE ]]; then
    # Save current time stamps to prevent radarr from identifying our simlink as new, and double-processing it
    LINKDIR=$(dirname "$LINKPATH")
    FOLDER_DATE=$(date -r "$LINKDIR" +@%s.%N)
    FILE_DATE=$(date -r "$LINKPATH" +@%s.%N)

    rm "$LINKPATH"
    ln -s "$PERMPATH" "$LINKPATH"

    touch --no-create --no-dereference  --date "$FILE_DATE" "$LINKPATH"
    touch --no-create --no-dereference  --date "$FILE_DATE" "$PERMPATH"
    touch --no-create --no-dereference  --date "$FOLDER_DATE" "$LINKDIR"
fi

A quick way to test scripts is to create a testing environment using the movie “Test (2013)”.

mkdir -p ~/test && cd ~/test && touch "Test (2013).nfo" "Test (2013).por.srt" "Test (2013).por.forced.srt" "Test (2013).eng.srt" "Test (2013).mkv" && cp -R ~/test /path/to/folder/to/import

or in bash:

mkdir -p ~/test && cd ~/test && touch "Test (2013)."{nfo,por.srt,por.forced.srt,eng.srt,mkv} && cp -R ~/test /path/to/folder/to/import

This way you can manually import this movie and trigger the script. You can just run it again to repopulate the files.
