From the Linux and Unix Users Group at Virginia Tech Wiki

[edit] Scripted Login
The following is a work in progress. Eventually, the following commands should yield a login.
$ curl -s -c cookies https://auth.vt.edu/login?service=https://my.vt.edu/Login | sed -nrf sedconf | xargs curl
The sedconf file's contents are below.
/name="lt"/s/.*value="([^"]*).*/-d "lt=\1"/p /name="_eventId"/s/.*value="([^"]*).*/-d "eventId=\1"/p /name="submit"/s/.*value="(^")*".*/-d "submit=\1"/p /action="/s/.*action="([^;]*)[^?]*(\??[^"]*).*/--url "https:\/\/auth.vt.edu\1\2"/p $a -d "username=bob" $a -d "password=bubba" $a -c cookies
Refer to the sed and curl manual pages for details on the various commands that drive this script.
