This is an example script that is able to get contacts,appointments,tasks as well as the global addressbook ical/vcard format.

NOTE:This example does the http request for the login as GET, so user name and password is logged in the apache log. The example only works for users that are created with the language en_US

~/bin> ./extract.sh --help
usage ./extract.sh serverurl user password
#!/bin/bash

SERVER=http://your.ox.server
USER=user@context
PASSWORD=userspw

test "$1" = "--help" && echo "usage $0 serverurl user password" && exit 1

test -z $1 || SERVER=$1
test -z $2 || USER=$2
test -z $3 || PASSWORD=$3

CURL='curl -b cookies -c cookies -H Expect: -s -L --location-trusted -k'

        |sed 's/^.*session\":\"\([0-9A-Fa-f]*\)\".*$/\1/'`
