Item Upload Bash Script Sample

Below is a sample script to upload items defined in JSON. By default it's configured to upload items defined in a JSON file (items.json) in the same directory as the script, to your local Elements instance. You can format the items in the JSON in the same way you see in the example earlier in this document.

This script will also update items if they already exist in the database.

#!/usr/bin/env bash

function post_item() {

    url=$1
    secret=$2
    definition=$3
    name=$(jq -r  '.name' <<< "${definition}")
    id=$(curl -k -X GET "${url}/item/${name}" | jq -r '.id')
    echo "Item id is ${id}"
    if [ -z "$id" ] || [ "$id" = "null" ]
    then
          echo "Creating new item..."
          curl -k -X POST \
          "${url}/item" \
          -H 'Cache-Control: no-cache' \
          -H 'Content-Type: application/json' \
          -H "Elements-SessionSecret: ${secret}" \
          -d "${definition}"
    else
          echo "Updating item..."
          item=$(jq --arg id ${id} '{id: $id} + .' <<< "${definition}")
          curl -k -X PUT \
          "${url}/item/${id}" \
          -H 'Cache-Control: no-cache' \
          -H 'Content-Type: application/json' \
          -H "Elements-SessionSecret: ${secret}" \
          -d "${item}"
    fi
    return $?
