Rather than using sed to change your original template file and then change it back why not create a new file with the changes and remove once you are done. Here I use $$ which expands to shells processID to ensure unique filename in case script is run simultaneously.
Also assuming TEXT is supposed to be replaced with the table names:
Since i'm new to scripting i'm findind it difficult to code a script. The script has to be an executable with 2 paramters passed to it.The Parameters are

2. The Data file name(.csv file)

VDETAPLIB(1) General Commands Manual VDETAPLIB(1)NAME
vdetaplib - Virtual Distributed Ethernet tap emulation library
SYNOPSIS
No synopsis
DESCRIPTION
vdetaplib is a library that emulates tap (tuntap level2 interface, see in kernel sources Documentation/networking/tun.c) and connects tap
virtual interfaces to vde networks.
To use it, the libvdetab.so library must be preloaded (sh, ksh or bash syntax):
export LD_PRELOAD=/usr/lib/vde2/libvdetap.so
(csh, tchs syntax):
setenv LD_PRELOAD /usr/lib/vde2/libvdetap.so
If you want to divert all tap requests to a single vde_switch set the variable VDEALLTAP to the vde socket.
(sh, ksh or bash syntax):
export VDEALLTAP=/tmp/vde.ctl
(csh, tchs syntax):
setenv VDEALLTAP /tmp/vde.ctl
It is possible to set each single interface to different vde_switches by setting the environment variable with the same name of the inter-
face.
(sh, ksh or bash syntax):
export tap0=/tmp/vde.ctl
export tap1=/tmp/myvde.ctl
export ppc=/tmp/ppc.ctl
(csh, tchs syntax):
setenv tap0 /tmp/vde.ctl
setenv tap1 /tmp/myvde.ctl
setenv ppc /tmp/ppc.ctl
It is also possible to specify port, group or mode for a given interface setting environment variables as in the following example.
(sh, ksh or bash syntax):
export tap0_port=5
export tap0_group=vde-net
export tap0_mode=0660
(csh, tchs, syntax):
setenv tap0_port 5
setenv tap0_group vde-net
setenv tap0_mode 0660
The variable to set the specific interface is checked first then VDEALLTAP. VDEALLTAP thus works as a default choice for the vde switch to
be used. If VDEALLTAP is not set and there is no specific environment variable (and for tun -- IFF_TUN interfaces) the kernel provided
interface is used. In this latter case access to /dev/net/tun is required, generally root access.
