Hi i am getting the following ouput

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.100.19.98 netmask fffffe00 broadcast 10.110.9.255

i want to hold the '10.100.19.98' in a variable

try this...

ip_addresss=`/sbin/ifconfig -a | awk ' /inet.*broadcast/ "{print $2}"'`

user@host> (/home/user) $ /sbin/ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 158.155.34.123 netmask ffff0000 broadcast 158.155.255.255
user@host> (/home/user) $ /sbin/ifconfig -a|awk '{if($1=="hme0:"){interface=1} if(interface==1 && $1=="inet"){print $2}}'
158.155.34.123
user@host> (/home/user) $

Here is the output of Solaris ifconfig and logic to get the IP of required interface, in my case hme0 is the interface

thanks @ itkamaraj
I am getting the output as few modification based on your code.

ifconfig -a | awk ' /(inet)(.*)broadcast/ {print $2}'

thanks @ kumaran_5555. But i don't under stand your logic and i am not able to get the output as per you mention method

 /sbin/ifconfig -a|awk '{if($1=="hme0:"){interface=1} if(interface==1 && $1=="inet"){print $2}}'

you have to change hme0 to e1000g0. The logic you have used may not work when you have more interface with broadcast enabled.

/sbin/ifconifg | sed '/ *inet/ ! d; /127\.0\.0\.1/d;s/ *inet \(.*\) n.*/\1/'
