Hi,
I'm pretty new to UNIX shell scripting and need some help. We have an Informatica interface that dumps any files that have errors into a directory. I need to check that directory periodically for any of up to 9 files that might be in it and run a specific process for each file found. The directory could (and hopefully would be) empty.

I've gotten some help from some of the folks here and have worked out some of the initial problems, but it goes into an endless loop and I have to stop it. I'm missing something.

Any help would be greatly appreciated.

Here is the test code without the actual processes:

Code:

#!/bin/ksh

ls /home/inform/LeanLogistic/bkp | while read filename
echo $filename
do
echo 'did do statement'

	if [ "$filename" = "CX_ORDER_LOAD_SHIPMENTexport.csv" ]
       then
       /usr/bin/echo "CX_ORDER_LOAD_SHIPMENT file." 
	elif [ "$filename" = "CX_CHARGEexport.csv" ]
	then 
	  /usr/bin/echo "CX_CHARGE file." 
	elif [ "$filename" = "CX_LOAD_HISTORYexport.csv" ]
	then
	  /usr/bin/echo "CX_LOAD_HISTORY file." 
	elif [ "$filename" = "CX_DEDICATED_EQUIPMENTexport.csv" ]
	then
	  /usr/bin/echo "CX_DEDICATED_EQUIPMENT file." 
	elif [ "$filename" = "CX_LOAD_NOTEexport.csv" ]
	then
	  /usr/bin/echo "CX_LOAD_NOTE file."
	elif [ "$filename" = "CX_PRODUCT_INFOexport.csv" ]
	then
	  /usr/bin/echo "CX_PRODUCT_INFO file." 
	elif [ "$filename" = "CX_RATE_CHANGE_REQUESTexport.csv" ]
	then
	  /usr/bin/echo "CX_RATE_CHANGE_REQUEST file."
	elif [ "$filename" = "CX_SERVICE_REQUESTexport.csv" ]
	then
	  /usr/bin/echo "CX_SERVICE_REQUEST file." 
	elif [ "$filename" = "CX_SERVICE_FAILUREexport.csv" ]
	then
	  /usr/bin/echo "CX_SERVICE_FAILURE file." 
	fi
echo 'did if statement'
done

Below is the output it produces when all 9 files are in the directory. It loops through and reads all the files, but then just keeps looping.
