if i have the command ifconfig eth0, what will the output be and how can i use either awk or grep to isolate and display the IP address, subnet mask and physical address of my host

This is a little clumsy, but may work:

Code:

ifconfig eth0 | head -n 2 \
| sed 'N;s/\n/ /;N;s/\n/ /' | awk '{print $7 " " $9 " " $5}' \
| sed -e 's/addr://g' -e 's/Mask://g'

Salut
