Bash script to refresh a Plex library, or specific path in a library. I use this in conjuction with qBittorrent to refresh a specific file or folder in my library so that Plex doesn't try to grab metadata for a half downloaded item. This happens if there are multiple items downloading to the same library.

plex_refresh.sh

#!/usr/bin/env bash

domain=
token=
library=$1
refPath=$2

libIndex=-1

echoerr() { echo "$@" 1>&2; }

# Match qBittorrent Category name to Plex library index
# (find by doing 'Get Info > View XML' on an item in each library
case "$library" in
        "Anime")
                libIndex=3;;
        "Movies")
                libIndex=1;;
        "TV Shows")
                libIndex=2;;
esac

# Validate that a library was specified, exit if not
if [ $libIndex -eq -1 ]; then
        echoerr "Invalid library name"
        exit 1
fi

# Check if a path was specified for a targeted refresh
if [ $refPath ]; then
        echo "Refreshing $refPath"
        curl --globoff "http://$domain:32400/library/sections/$libIndex/refresh?path=$refPath&X-Plex-Token=$token"
else
        echo "Refreshing $library @ library section $libIndex"
        curl --globoff "http://$domain:32400/library/sections/$libIndex/refresh?X-Plex-Token=$token"
fi

usage:

plex_refresh.sh "<library name>" "[path]"

path is optional, if not supplied the entire library will be refreshed.
