Continuous Integration environment with svn on linux

On my previous post I wrote a way I used to create a CI environment that'd export the entire application to a web location after each commit. I was working then for windows. Now, I have created a setup for Linux - with addition this time the post-commit will only update those files that are actually committed. Following is the post-commit script I got on Stackoverflow:

	#!/bin/sh
	REPOS="$1"
	REV="$2"
	# A - Item added to repository
	# D - Item deleted from repository
	# U - File contents changed
	# _U - Properties of item changed; note the leading underscore
	# UU - File contents and properties changed
	# Files and directories can be distinguished, as directory paths are displayed with a trailing "/" character.
	LOOK=/usr/local/svn/bin/svnlook
	SVN=/usr/local/svn/bin/svn
	DEV=/var/www/test
	cd /location/to/your/svnrepo
	for changes in `$LOOK changed $REPOS | awk '{print $1 "=" $2;}'`;
	do
	len=${#changes}
	idx=`expr index "$changes" =`;
	directory=${changes:$idx};
	action=${changes:0:$idx-1};
	if [ ${changes:len-1} = '/' ]
	then
	case "$action" in
	"A" ) \
	mkdir --mode=775 -p $DEV/$directory;
	chown nobody:nobody $DEV/$directory;
	chmod 775 $DEV/$directory;
	;;
	"D" ) \
	rmdir $DEV/$directory;
	;;
	esac
	else
	case "$action" in
	"A"|"U"|"UU" ) \
	$SVN export --force --non-interactive -r HEAD -q file://$REPOS/$directory;
	BASE=`basename $directory`;
	DIR=`dirname $directory`;
	chown nobody:nobody $BASE;
	chmod 775 $BASE;
	mkdir --mode=775 -p $DEV/$DIR;
	cp -f --preserve=ownership $BASE $DEV/$DIR;
	unlink $BASE;
	;;
	"D" ) \
	rm -f $DEV/$directory;
	;;
	esac
	fi
	done
	exit 0
