Need help for a bash script - OVZ container

Taz

So, I am writing a simple setup script for ovz container (bash code?), Right now I am stuck at one place,

I have a configuration file that goes like this

Herpy Derp

derp derp
derpy derp
serverip= #
blah blah
blah blah

So now, I need something that would do this

echo serverip= x.x.x.x > /etc/service.conf

and

iptables -t nat -A POSTROUTING -s 1.2.3.0/24 -j SNAT --to "serverip"

How would the script find and replace server ip for both case?

Is this a template? And you want to replace # with the server ip?

So now, I need something that would do this

echo serverip= x.x.x.x > /etc/service.conf

Or is 'service.conf' the above?

Sorry, it's really unclear to me what the flow is supposed to be....

Taz

Kinda,
Is there anyway to echo servers main ip inside that config file using commands like ip addr show?

Taz

Well

serverip= #

would be replaced by

serverip= x.x.x.x

@Zen said: Yeah but you're still being unclear what the objective is entirely, just tell us exactly what you want us to do in order.

This is for an auto setup openvpn script.

if you place inside a script you can pass a parameter:

#!/bin/sh
a=$1
sed -e "s/=#/=$a/" /path/to/template

I only guessing still at what you want, but...

template.txt

Herpy Derp
derp derp
derpy derp
serverip=#SERVERIP#
blah blah
blah blah

script.sh

#!/bin/bash

SERVERIP=$1
TEMPLATE=`cat template.txt`

if [ "$SERVERIP" ]; then
    CONFIG=`echo "$TEMPLATE" | sed "s/#SERVERIP#/$SERVERIP/"`
    echo "$CONFIG"
else
    echo "Usage: script.sh [ip address]"
fi

exit 0

Usage:

[sleddog@home:~/test] sh script.sh 192.168.1.100
Herpy Derp
derp derp
derpy derp
serverip=192.168.1.100
blah blah
blah blah

I could write it for you, but that would be cheating, use a foreach line statement and awk. If I recall properly you can parse until $1 is your serverip, then read $3 and then that's your IP.

It's better marketing than you could ever dream of doing.

Unless your clients are as dumb as you they'll know not to touch your farcical "company" with a barge pole.
