In newer versions of svn lib (running under windows), i just need replace this:
svnadmin dump #path# #file#.dump

with this:
svnadmin dump #path# > #file#.dump

Made slight correction to this script however when coping and pasting this script pay attention to the single quotes that need to be adjusted around ‘#!/bin/sh’ , these ‘ quotes should have no curve. The blog text filters are changing them probably to avoid sql injection attacks but the script won’t work unless you have the right single quote around the line: echo ‘#!/bin/sh’

#!/bin/bash
#script for GNU/Linux/nix inspired by this excellent article
cd /tmp
svn_repo_name=”test_repo”
source_url=”http://svn.example.org/example”

DATEC=”/bin/date”
DATE=”`${DATEC} +%Y-%m-%d_%Hh%Mm`”
echo “`${DATEC} +%Y-%m-%d_%Hh%Mm`”

echo “mkdir $svn_repo_name”
mkdir $svn_repo_name

echo “svnadmin create $svn_repo_name”
svnadmin create “$svn_repo_name”

echo “echo ‘#!/bin/sh’ > ${svn_repo_name}/hooks/pre-revprop-change”
echo ‘#!/bin/sh’ > “$svn_repo_name”/hooks/pre-revprop-change

echo “sudo chmod +x {$svn_repo_name}/hooks/pre-revprop-change”
sudo chmod +x “$svn_repo_name”/hooks/pre-revprop-change

echo “svnsync init file:////tmp/$svn_repo_name ${source_url}”
svnsync init file:////tmp/”$svn_repo_name” ${source_url}

echo “svnsync sync file:////tmp/$svn_repo_name”
svnsync sync file:////tmp/$svn_repo_name

echo “svnadmin dump $svn_repo_name > {$svn_repo_name}_${DATE}”
svnadmin dump “$svn_repo_name” > {$svn_repo_name}_${DATE}
