/sbin/ifconfig eth0| grep 'inet addr:' |sed 's/inet addr/IP address/;s/Mask\
Subnet Mask/'

That backslash on the end of line one must be the character on the line so that it is quoting the newline character.

You don't need grep:

Code:
temp=$(ifconfig eth0)
temp=${temp#*addr:}
ip=${temp%% *}
temp=${temp#*Bcast:}
bc=${temp%% *} 
printf "IP address: %s\n" "$ip"
printf "Subnet Mask: %s\n" "$bc"
