Help with script

Ragni Singh — Mon, 02 Apr 2012 00:59:14 GMT

I have this script but instead of setting this for one interface, I would like for it to prompt me for the following interfaces..

eth0, etc1,eth2,eth3, etc.

How can I do this with the script provided? Thanks a lot, or if anyone out there that has a script in place and would like to share.

hostname=""
ip=""
netmask=""
gw=""
answer="n"
device="eth0"
hwaddr=`ifconfig $device | grep -i hwaddr | sed -e 's#^.*hwaddr[[:space:]]*##I'`
dns1="64.94.1.1"
dns2="64.94.1.3"

curTTY=`tty`
exec < $curTTY > $curTTY 2> $curTTY
clear

while [ "x$answer" != "xy" ] && [ "x$answer" != "xY" ] ; do
        echo -n "enter hostname: "; read hostname
        echo -n "enter ip: "; read ip
        echo -n "enter netmask: "; read netmask
        echo -n "enter default gw: "; read gw
        echo -n "hard set '100baseTX full-dulplex' [y/n] " ; read opts
        echo

        echo You entered:
        echo -e "\thostname: $hostname"
        echo -e "\tip: $ip"
        echo -e "\tnetmask: $netmask"
        echo -e "\tdefault gw: $gw"
        echo -e "\tset 100baseTX full-duplex: $opts"
        echo -n "Is this correct? [y/n] "; read answer
done

sed -i -e 's#^$HOSTNAME=$.*$#\1'"$hostname"'#' /etc/sysconfig/network
echo GATEWAY=$gw >> /etc/sysconfig/network

echo DEVICE=$device > $scrFile
echo BOOTPROTO=static >> $scrFile
echo ONBOOT=yes >> $scrFile
echo NM_CONTROLLED=no >> $scrFile
echo HWADDR=$hwaddr >> $scrFile
echo IPADDR=$ip >> $scrFile
echo NETMASK=$netmask >> $scrFile
echo USERCTL=no >> $scrFile
echo DNS1=$dns1 >> $scrFile
echo DNS2=$dns2 >> $scrFile

%end

You could get all of them from the command line. Or you could read all of them after a prompt. Or prompt one at a time.

From the command line:

...

while [ $# -gt 0 ]; do

device=$1

hwaddr=`ifconfig $device | grep -i hwaddr | sed -e 's#^.*hwaddr[[:space:]]*##I'`

...

shift

done
