GaurAVS,
I don't know what were the reaosns that made you selected this option, question did you try using any other options to move data from source to destination. Couple of questions for you?
1. One single export dump for each schema user or is it more than one file?
2. I assume from your earlier post, you got more than 50 schema users in your database?
Here is simple bash script, assuming you have one export dump file for each schema user. Make a directory call data and move all the dump file, please read script carefully for more instruction and modify according to your needs.
In addition before running this script on linux box run follwoing from command prompt
$dos2unix import.sh
#!/bin/bash
function importfile
     echo "importing $file for user $1"
     imp $1/$2 full=y file=$file log=./data/`basename $file dmp`log
     test=$?
     if [ $test -ne 0 ]
     then
            echo "Importing for user $1 failed ..."
         exit 1;
     fi
function listfile
    # you have to supply username and password here
       for file in ./data/*.dmp
       do
         echo "exporting $file for $1"
         # If you used username as filename for each export dump
          unset username
          +username=`basename $file .dmp`
          echo "Username is set to $username"
          # Now to get password for this username ; you can create a file with
          # this format username=password
          # $1 -- Username
          # $2 -- Password
          unset pw
          pw=`cat ./data/pwd.txt.txt|grep $username|cut -d'=' -f2`
          echo "Password is set to $pw"
          # You have to write a small function to get username and password
          importfile $username $pw
           done
