Thanks a lot Franklin52 for the awk command. I need to take the ipaddress from the user, so is it possible to use variables in this command.

I am not very good at the awk commands, but I have tried the following.I guess awk variables are different so I imported the ip variable, but it does not evaluate the unix command in there.

Code:
ip=234.235.34.56
export ip
awk '/ONBOOT=no/{
print
print "DEVICE=eth0"
print "BOOTPROTO=static"
print "IPADDR=`echo$ip`"
print "NETMASK=255.255.255.0"
print "GATEWAY=234.235.34.1"
next
}1' temp > temp1

Output of the file:

Code:
ONBOOT=no
DEVICE=eth0
BOOTPROTO=static
IPADDR=`echo$ip`
NETMASK=255.255.255.0
GATEWAY=234.235.34.1

Can you please help..

ROUTE.CONF(5)						      BSD File Formats Manual						     ROUTE.CONF(5)

NAME
route.conf -- static routes config file DESCRIPTION
The route.conf file is read by the staticroute rc.d script during system start-up and shutdown, and is intended for adding and removing static routes. FILE FORMAT Lines starting with a hash ('#') are comments and ignored. Lines starting with a plus sign ('+') are run during start-up, while lines start- ing with a minus sign ('-') are run during system shutdown. If a line starts with a '!', the rest of the line will get evaluated as a shell script fragment. All other lines are passed to route(8). During start-up, they are passed behind a ``route add -'' command and during shut- down behind a ``route delete -'' command. FILES
/etc/route.conf The route.conf file resides in /etc. /etc/rc.d/staticroute rc.d(8) script that parses route.conf. EXAMPLES
In this example, the interface for the desired routing changes is set, the IP address on that interface is determined, and a route is added during startup, or deleted during system shutdown. # Set interface and determine current IP address for added route. !ifname=bnx0 !ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}') net 10.10.1 -interface ${ipaddr} In this example, IP forwarding is turned on during start-up, and a static route added for 192.168.2.0. During system shutdown, the route is removed and IP forwarding turned off. # Turn on/off IP forwarding. +sysctl -w net.inet.ip.forwarding=1 -sysctl -w net.inet.ip.forwarding=0 net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2 SEE ALSO
