thank you Scrutinizer. i just started learning the shell scripting.
so far i have written a script to find a servername from a text file and add a new server name (ex it csslu258 exists, add csslu259 or if csslu259 exists add csslu258)

Code:
#!/bin/sh
# this program will search for the servername in a directory and adds a new cluster servername 
let i=0
echo "Enter the filename:"
read FILENAME
echo "enter the server name:"
read SERVERNAME
a=$SERVERNAME
if grep $SERVERNAME $FILENAME > /dev/null ;then 
  echo "file contains server csslu$SERVERNAME"
  rem=$(( $SERVERNAME%2 ))
  if [ $rem -eq 0 ]
  then
    let i=a+1
  else
    let i=a-1
  fi
  if grep $i $FILENAME > /dev/null ; then
    echo "the sever name csslu$i already exists nothin to add"
  else
    echo "csslu$i" >>$FILENAME
  fi
  echo "printing tail of $FILENAME to check if the cluster is addedd..."
  tail -3 $FILENAME
else
  echo "csslu$SERVERNAME not found"
fi

my inputs are
filename -sample.txt
servername-258
. i need to do the same for all the files in the directory.
if i input file name as *.txt, the scripts creats a new file *.txt and add the sever name

hope you could understand the requirement.

thank you

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $name    = $ui->which;	    # Find out what shell you loaded

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
