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
1. The Control file name(.ctl file)
2. The Data file name(.csv file)

vde_plug
VDE_PLUG(1) General Commands Manual VDE_PLUG(1)NAME
vde_plug - Virtual Distributed Ethernet plug (two plugs creates a vde cable)
SYNOPSIS
vde_plug [ -p portnum ] [ -g group ] [ -m octal-mode ] [ socketdir ]
DESCRIPTION
A vde_plug is a plug to be connected into a VDE switch. All the data that is catched by the plug is written in its stdout and everything
from stdin is injected in the switch.
This tool has been designed to be used together with dpipe (1) to interconnect a second vde_plug to another switch, working as a virtual
ethernet crossed cable between the two switches.
The command
dpipe vde_plug = vde_plug /tmp/vde2.ctl
connects two local switches: the former is using the standard control socket /tmp/vde.ctl while the latter is using /tmp/vde2.ctl.
The command
dpipe vde_plug = ssh remote.machine.org vde_plug
connects two remote switches. If the two vde_switches run as daemon and they are connected to tap interfaces a level 2 encrypted tunnel is
established.
vde_plug can also be established as a login shell for users. The following command works as in the previous example
dpipe vde_plug = ssh vdeuser@remote.machine.org vde_plug
where vdeuser is the user with vde_plug as standard shell. All the remote accesses are logged by syslog at the beginning and at the end of
each session. Attempt to login without the command vde_plug at the end or trying to execute something else are blocked and the attempt is
logged into syslog.
OPTIONS -p portnum
It is possible to decide which port of the switch to use. When this option is not specified the switch assigns the first available
unused port (if any). It is possible to connect several cables in the same switch port: in this way all this cables work concur-
rently. It means that packet can result as duplicate but no ARP table loops are generated. Is useful when vde is used for mobil-
ity. Several physical interfaces can be used at a time during handoffs to prevent hichups in connectivity.
-g group
group ownership of the communication socket. For security when more want to share a switch it is better to use a unix group to own
the comm sockets so that the network traffic cannot be sniffed.
-m octal-mode
octal chmod like permissions for the comm sockets
socketdir
(This option can be also set as: -sock socketdir ) specify the directory which contains the UNIX socket to be used by local programs
for joining the VDE. The default value is "/tmp/vde.ctl", which corresponds to the socket "/tmp/vde.ctl/ctl" (or /var/run/vde.ctl
when the vde_switch runs as a shared daemon). It is possible for users to redefine their default switch as ".vde-2/stdsock" in
their home directory. If exist, this directory (or symbolic link to the actual directory) is used as the default value for the user.
