API endpoint to scan a single library

[Azruzagar]

I ran into the same problem, but I gave the code to Chat-GPT to rewrite.

Code:

#!/usr/bin/env bash
set -o errexit
set -o nounset
set -o pipefail

JELLYFIN_SERVER="http://server_ip"
API_KEY="YOUR-API-Key"

trap 'printf "Script interrupted.\n" >&2; exit 1' INT TERM

fetch_libraries() {
    local response
    if ! response=$(curl -s -H "X-Emby-Token: $API_KEY" "$JELLYFIN_SERVER/Library/VirtualFolders"); then
        printf "Failed to retrieve libraries from Jellyfin server.\n" >&2
        return 1
    fi
    if [[ -z "${response//[[:space:]]/}" ]]; then
        printf "Empty response received from Jellyfin server.\n" >&2
        return 1
    fi
    printf "%s" "$response"
}

extract_names() {
    local data="$1"
    local names
    if ! names=$(printf "%s" "$data" | grep -o '"Name":"[^"]*"' | sed 's/"Name":"\(.*\)"/\1/'); then
        printf "Failed to extract names from JSON response.\n" >&2
        return 1
    fi
    if [[ -z "${names//[[:space:]]/}" ]]; then
        printf "No library names found in JSON response.\n" >&2
        return 1
    fi
    printf "%s" "$names"
}

extract_ids() {
    local data="$1"
    local ids
    if ! ids=$(printf "%s" "$data" | grep -o '"ItemId":"[^"]*"' | sed 's/"ItemId":"\(.*\)"/\1/'); then
        printf "Failed to extract IDs from JSON response.\n" >&2
        return 1
    fi
    if [[ -z "${ids//[[:space:]]/}" ]]; then
        printf "No library IDs found in JSON response.\n" >&2
        return 1
    fi
    printf "%s" "$ids"
}

print_libraries() {
    local names="$1"
    local ids="$2"
    paste <(printf "%s\n" "$names") <(printf "%s\n" "$ids") | while IFS=$'\t' read -r name id; do
        printf "Name: %s | ID: %s\n" "$name" "$id"
    done
}

scan_library() {
    local library_id="$1"
    if [[ -z "${library_id//[[:space:]]/}" ]]; then
        printf "Library ID not provided. Exiting.\n" >&2
        return 1
    fi
    printf "Starting scan of library %s ...\n" "$library_id"
    if ! curl -s -X POST \
        "$JELLYFIN_SERVER/Items/$library_id/Refresh?Recursive=true&ImageRefreshMode=Default&MetadataRefreshMode=Default&ReplaceAllImages=false&RegenerateTrickplay=false&ReplaceAllMetadata=false" \
        -H "Content-Type: application/json" \
        -H "X-Emby-Token: $API_KEY" >/dev/null; then
        printf "Failed to start scan for library %s.\n" "$library_id" >&2
        return 1
    fi
    printf "Scan started (check the Jellyfin dashboard for status).\n"
}

main() {
    printf "Retrieving available libraries...\n"
    local libraries names ids library_id
    libraries=$(fetch_libraries) || return 1
    names=$(extract_names "$libraries") || return 1
    ids=$(extract_ids "$libraries") || return 1
    print_libraries "$names" "$ids"
    printf "\n"
    read -r -p "Enter the ID of the library to scan: " library_id
    scan_library "$library_id" || return 1
}

main "$@"

Code:
