I think your logic is wrong. You grep for em1 and try to display the address if not found. How should this work?

Try the following which is a bit shorter than your version:

if /sbin/ifconfig | grep -q em1; then
        echo -e "

Address = $(/sbin/ifconfig em1 | awk '/inet addr:/ {print substr($2,index($2,":")+1)}')

        echo -e "

Address = $(/sbin/ifconfig eth0 | awk '/inet addr:/ {print substr($2,index($2,":")+1)}')
