#!/bin/bash# Script for retrieving all files on a an ftp server then deleting them.
#
# Requires ncftp and stock ftp client.
#
# We have to do some funkyness since there is no easy way of recursively deleting
# remote directories. We use ncftp to download all files and delete them on successfull
# download. This ,however, leaves empty directories. So we download the empty directory
# tree to FSTREEDIR to list all directories to delete(we can't trust the download directory
# because other directories may exist there). Those directories are then passed to the
# usual ftp client to delete.
# @todo - store credentials in a file
FTPSERVER=10.0.1.150
