How can I see the repository path of a local copy?

Use

svn info

For those who are looking for a way to find this out programmatically and reliably, this command gives you exactly the repository root, nothing else:

svn info --show-item wc-root

For repository root :

Linux : svn info | grep 'Repository Root' | awk '{print $NF}'

Windows : svn info | findstr /C:"Repository Root: "
