Clearing all messages from a queue through Shell Script

I have written a shell script to find out how many messages are struck in queue and purging/deleting messages from queue.

 Download the following script and store it in a location such as /usr/local/bin.

 Provide the file permissions and ownership for this script as you see fit. In this example, they are:

$ chmod 755 /usr/local/bin/clear-mq-messages.sh

$ chown mqm:mqm /usr/local/bin/clear-mq-messages.sh

$ ls -l /usr/local/bin/clear-mq-messages.sh

-rwxr-xr-x   1 mqm      mqm            1296 Oct 30 14:34 clear-mq-messages.sh

#!/usr/bin/ksh echo -e "\nPlease enter the \"queuemanager\" !!!"                 read queuemanager echo -e "\nPlease enter the \"input_queue\" !!!"         read inputqueue struck_message=`echo  "DISPLAY QL($inputqueue) CURDEPTH" | runmqsc $queuemanager | grep 'CURDEPTH(' | sed 's/.*CURDEPTH//' | tr -d '()'` if [ $struck_message = "0" ]; then     echo -e "===============================================" echo "now no messages in " $inputqueue echo -e "===============================================" echo -e "\n\nThank you!!! Bye!!!\n" exit 0 else echo -e "==============================================="     echo "the" $inputqueue "CURDEPTH count is" $struck_message echo -e "===============================================" fi echo -e "Would you really like to flush the $inputqueue? <y/N> " read prompt if [[ $prompt == "y" || $prompt == "Y" || $prompt == "yes" || $prompt == "Yes" ]] then echo -e "************************************************" echo "clear qlocal($inputqueue)" | runmqsc $queuemanager  echo -e "************************************************"                 struck_message2=`echo  "DISPLAY QL($inputqueue) CURDEPTH" | runmqsc $queuemanager | grep 'CURDEPTH(' | sed 's/.*CURDEPTH//' | tr -d '()'` echo "Now the CURDEPTH count is" $struck_message2 echo -e "************************************************" else echo -e "\n\nThank you!!! Bye!!!\n\n"                   exit 0 fi

Let see how this script will work

while script executing time this script will ask QueueManager name & queue name. 

 Let see CURDEPTH  count only....

If CURDEPTH count is zero, the script will work as below
