use case: in ibm mq i want to get all messages from DLQ. shunt them to 2 different queues. below is my implementation:

 #!/bin/bash
 #Function to browse messages one at a time and shunt them accordingly

function browseMessages {
  echo "Browsing messages from ${source_queue}"

  while : ; do

    message=$(${JAVA_HOME}/bin/java -jar -Dmq.queue.manager=$mqManager -Dmq.port=$mqPort 
    -Dmq.queue.name=$source_queue -Dmq.host=$mqHost -Dmq.channel=$mqChannel          
    ${APP_PATH}/MQUtil-$jarversion.jar BROWSE -Dmq.count=1 | head -n 1)

    if [ -z "$message" ]; then
      echo "No more messages to browse, exiting loop."
      break
    fi

    echo "BROWSE: ${message}"

    if [[ "$message" == *'BusinessEventType="Amend"'* ]]; then
      shuntMessage "$message" "$AMEND_queue"
    else
      shuntMessage "$message" "$NEW_queue"
    fi
  done
  }

Function to shunt individual messages to the specified queue

 function shuntMessage {

   local message=$1
   local destination_queue=$2
   echo "Shunting message to ${destination_queue}"
   echo "$message" | ${JAVA_HOME}/bin/java -jar -Dmq.queue.manager=$mqManager -Dmq.port=$mqPort 
   -Dmq.queue.name=$source_queue -Dmq.host=$mqHost -Dmq.channel=$mqChannel 
   -Dmq.shunt.queue.name=$destination_queue ${APP_PATH}/MQUtil-$jarversion.jar SHUNT
 }

while i build a docker image using this shell script and run it it stucks at
browsing message 0…..

when i tested the browsing functionality indivisually.. it works..

function browseTop3Messages {
  local queue=$source_queue
  local count=3
  local action="BROWSE"

#Invoke the MQUtil jar with the BROWSE command and limit the count to 3
 ${JAVA_HOME}/bin/java -jar -Dmq.queue.manager=$mqManager -Dmq.port=$mqPort 
  -Dmq.queue.name=$queue  -Dmq.host=$mqHost -Dmq.channel=$mqChannel
  -Dmq.count=$count 
  ${APP_PATH}/MQUtil-${jarversion}.jar ${action}
}

is the issue with shunting the messages??

when i tried just to browse it worked. but when i try to browse and filter and then shunt.. it does not work.. my doubt is how i am am trying to shunt the message. please suggest
