Bash script to call rest endpoint for each id in text file

I needed to write an admin utility script to delete documents from a content management system.  First, the list of document ids were retrieved from the application database; Second, the list of ids were used as input to a bash script to make REST calls to delete the documents.

Environment:
MySql 5.7.10
RHEL 7

STEPS:

1. Retrieve list of ids from the database and save to uuids.txt, one id on each line. The ids were alfresco cmis unique ids (with unique nodeRef id, ;,  and version number), they look like "workspace://SpacesStore/aa3e765f-c628-44c2-bc66-17d622ca2210;1.0".  I needed documents created after a certain date, and only the unique id portion after the "SpacesStore/" and prior to the ";1.0" of the unique id.  Below is the MySQL select statement:
   
   select substring_index(substring_index(alf_node_id, 'SpacesStore/', -1),
                          ';1.0', 1), created_dt from cherryshoe_documents where created_dt >= '2017-03-18 00:00:00' order by created_dt desc;
   
   
2. The bash script is below, it incorporates a curl call to a REST DELETE endpoint with basic authentication.
   
   delete.sh

   
   #!/usr/bin/bash
   # Calls a repository rest endpoint to delete node(s).
   # Takes in an input text file of one id per line.
   
   username=admin
   password=admin
   protocol=http
   #hostname can contain port
   hostname="localhost:8080"
   
   echo username=$username, password=$password, protocol=$protocol, hostname=$hostname
   
   if (( "$#" != 1 ))
   then
       echo "Usage Info: Enter in filename"
   exit 1
   fi
   
   filename="$1"
   
   echo "Starting Node Delete..."
   while read -r line
   do
       uuid="$line"
       endpoint=$protocol://$hostname/alfresco/s/api/node/workspace/SpacesStore/$uuid
       # contains a \r (CR) at the end (0d). Remove it with
       endpoint=${endpoint%$'\r'}
       echo $endpoint
   
       echo "#######START $uuid"
       curl -u $username:$password -i -X DELETE $endpoint
       echo "#######END $uuid"
   
   done < "$filename"
   
   echo "DONE"
