Hi Ravinder,

Thanks for your reply. I have tried it using
Code:
while

loop as below but did not get the result.

Code:
     while IFS = read -r line
      do
      echo "$line"
      done < "$file"

My input file looks like below. I am giving a few lines of it. Original file contains 210 lines.

Code:

After storing the file contents to a variable , I want to use grep command to remove some of the records in field 2 and then i want to append some other file to the resulting file.

When i am asking the user to enter the file manually and read the file with the
Code:
read

command, i am able to do it but when i am trying the script to read itself,can not able to do.

Please let me know your thoughts on this.

Thanks in advance.

Temporary(4)						     Kernel Interfaces Manual						      Temporary(4)

NAME

       Temporary - Stores data files during transfers to remote systems

SYNOPSIS

       /usr/spool/uucp/SystemName/TM.xxPID.000

DESCRIPTION

       The  uucp  Temporary  (TM.*) files store data files during transfers to remote systems.	After a Data (D.*) file is transferred to a remote
       system by the uucico daemon, the uucp program places it in a subdirectory of the uucp spooling directory named  /usr/spool/uucp/SystemName,
       where  the SystemName directory is named for the computer that is transmitting the file.  The uucp program creates a temporary data file to
       hold the original data file.

       The full pathname of the temporary data file is in the following format: /usr/spool/uucp/SystemName/TM.xxPID.000

       where the SystemName directory is named for the computer that is sending the file, and TM.xxPID.000 is the name of the file;  for  example,
       TM.00451.000.  The PID variable is the process ID of the job.

FILES

       Describes accessible remote systems Contains uucp command, data, and execute files Contain data to be transferred.  Contain files that uucp
       has transferred

RELATED INFORMATION
