Have a dynamic ip and want to extract only the ip address from say
ifconfig?
/sbin/ifconfig | grep xxx | cut -c 21- | cut -c -14
where xxx = the first quad of your isp. Ex. my isp is rio.com 208.137.0.0, so
xxx = 208
I have a series of scripts to extract the dynamic ip every time pppd fires and
insert the new address into some files and ftp the new files to my static web
pages. This allows me to make services on my local box accessible without
static routing.
