Finding the DHCP address

• Classic Unix!

• Look in ifconfig output: ifconfig

• Pipe to grep: |grep - A 2 "eth0"

• Pipe to awk: |awk '/inet/ {print $2}'

• Pipe to sed: |sed - e s/addr://

• Put it all together and put result in an environmental variable:

• IPADDR =" `ifconfig|grep - A 2 "eth0"|awk '/inet/ {print $2}' \ |sed - e s/addr:// ` "

• (For reference, output of ifconfig looks like:

• eth0 Link encap:Ethernet HWaddr 00:E0:98:05:7B:0F

• inet addr:192.168.7.35 Bcast:192.168.7.255 Mask:255.255.255.0

• UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

• etc )
