What do you want to insert?
I want to insert the first argument, which will be a line of text
Where do you want to insert it?
In the middle of the second argument which is a text file
I assume that you do not want it in the middle of the second argument, but in the middle of the file pointed to by the second argument.
If that is the case, you need to find out how many lines are in the file, use head to read that number of lines; insert the text; use tail to get the rest of the file, or use awk.

vdetaplib
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.
