Determine total size of SVN directory/trunk

This is my modification to the answer. It reports how many files are below a certain directory in svn and the total size.

svn list -vR svn://svn/repo/subdir|awk '{if ($3 !="") sum+=$3; i++} END {print "\ntotal size= " sum/(1024*1024)" MB" "\nnumber of files= " i/1000 " K"}'

Using the below, you can determine the size of individual files.

svn list --verbose --recursive http://svn/repo/path

Maybe you can look around this command to find a way?
