SVN relocate for a list of directories

relocate.sh

#!/bin/bash

# This script is used to relocate a Subversion repository from one
# filesystem location to another.  It is intended to be run from the
# command line, but it can be run from any other program too.
# You can prepare the new repository location using:
#
# export NEW_SVN_LOCATION=file:///path/to/new/repository
#
# The script can be run using the following command - The list
# will be created using find for the .svn directories therein:
# bash ./relocate.sh /path/to/directory/list
#
# Alternatively run:
# env NEW_SVN_LOCATION=file:///path/to/new/repository bash ./relocate.sh /path/to/directory/list

# ask for new location
NEW_SVN_LOCATION=${NEW_SVN_LOCATION:-$(read -p "Please enter the new SVN location: " NEW_SVN_LOCATION ; echo $NEW_SVN_LOCATION)}

# remove trailing slash
