New requirement!! Need help

Thanks for the response...Now i have a requirement something like this. I have a script as below:

#!/bin/bash -vx
##VARIABLES used below are defined in my profile and am importing them before i use them
rm -f list.log
#Extract the RPMs from RPM Database on each of the server
for i in $SERVER; do
echo -n "$i" >> list.log
echo "" >> list.log
ssh $i 'rpm -qa | grep '$CURRENT_VER' ' >> list.log
done

#Extract Info from the Delivery Server
rm -f $DELIVERY_LOG
for j in $WEBDAV_SERVER; do
echo $DELIVER_DIR
ssh <user_name>@$j 'find '$DELIVER_DIR' -type f -name "vst3*.rpm" -printf %f\\n ' >> $DELIVERY_LOG
done

# Compare the files delivery and list two get the difference.
Now here is what i am facing the problem.
1. I need to sort the $DELIVERY_LOG taking only higher version of the RPM and make it $FINAL_LOG
2. I need to compare $FINAL_LOG with the list.log and i should get the output as below
the RPM in $FINAL_LOG is missing on the server *$i
Will i have to create a property file which has which all RPMs are present on each server first? or is there any other method

Could anyone help me out in this

endusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
