Not that it really matters, but you don't need grep and tr:
ip=`ifconfig $1 | awk '/inet addr/{sub(/addr:/,""); print $2}'`
or even shorter
ip=`ifconfig $1 | awk -F'[: ]+' '/inet addr:/{print $4}'`
and unless you need the ip in a variable for other purposes, you can
do away with the echo as well:
ifconfig $1 | awk -F'[: ]+' '/inet addr:/{print "your ip on '$1' is "$4}'
Also, it might be prudent to use full path for ifconfig,
i.e. /sbin/ifconfig, as /sbin may not be in $PATH.
