Not to remove Files based on property value
Hi All,

Need your help to fix one script.

Main agenda is:
1. Read a property file.
2. Delete all files in directory except the name from Property file.

I am trying to read property file for value then deleting all files from directory except THAT value/name.

I have tried so far as below:
Property File i.e., earBuild.properties
Code:
#EAR Names
earName=XYZ.ear

OR
Property file can be with Multiple Ear names as:
Code:
#EAR Names
earName=XYZ.ear
earName=ABC.ear


I have written below shell script but loop is deleting all files in directory.

Code:
#!/bin/bash

echo "Reading property file at `pwd`"
ls -lrt

find /tmp/s/earProps/ -name earBuild.properties

FILE_NAME="earBuild.properties"
echo "EAR property file is: $FILE_NAME"

EARPATH="/tmp/s/props/ears/"

# Key in Property File
KEY="earName"

# Variable to hold the Property Value
prop_value=""

getProperty()
{
        prop_key=$1
        prop_value=`cat ${FILE_NAME} | grep ${prop_key} | cut -d'=' -f2`
}

getProperty ${KEY}
echo "KEY = ${KEY} ; Value = " ${prop_value}

for i in ${prop_value}; do
	find $EARPATH -type f ! -name $i -exec rm -rf {} \;
	echo "Value of I in loop is $i"
done


I am no bound to use find or rm or even for loop. Looking for the solution.
Appreciate help in advance.

Thanks

ptree_create_prop

ptree_create_prop(3PICLTREE)				  PICL Plug-In Library Functions			      ptree_create_prop(3PICLTREE)

NAME

       ptree_create_prop, ptree_destroy_prop - create or destroy a property

SYNOPSIS

       cc [ flag... ] file... -lpicltree [ library... ]
       #include <picltree.h>

       int ptree_create_prop(ptree_propinfo_t *pinfo, void *valbuf,
	    picl_prophdl_t *proph);

       int ptree_destroy_prop(picl_prophdl_t proph);

DESCRIPTION

       The  ptree_create_prop()  function creates a property using the information specified in pinfo, which includes the name, type, access mode,
       and size of the property, as well as the read access function for a volatile property. The value of the property is specified in the buffer
       valbuf,	which  may  be	NULL  for volatile properties. The handle of the property created is copied into the location given by proph.  See
       libpicltree(3PICLTREE) for more information on the structure of ptree_propinfo_t structure.

       The ptree_destroy_prop() function destroys the property specified by the  handle  proph.   For  a  table  property,  the  entire  table	is
       destroyed. The property to be destroyed must have been previously deleted.

RETURN VALUES

       Upon successful completion, 0 is returned. On failure, a non-negative integer is returned to indicate an error.

       PICL_STALEHANDLE is returned if the handle is no longer valid. This occurs if the PICL tree was refreshed or reinitialized.

       PICL_INVALIDHANDLE is returned if the specified handle never existed.

ERRORS

       PICL_NOTSUPPORTED     Property version not supported

       PICL_VALUETOOBIG      Value exceeds maximum size

       PICL_NOTPROP	     Not a property

       PICL_CANTDESTROY      Attempting to destroy before delete

       PICL_RESERVEDNAME     Property name is reserved

       PICL_INVREFERENCE     Invalid reference property value

       PICL_INVALIDHANDLE    Invalid handle

       PICL_STALEHANDLE      Stale handle

       PICL_FAILURE	     General system failure
