How to edit svn externals of a folder using powershell

Question

In order to do a build, I checkout a svn repository which has multiple folders.One of folders has properties -> svn externals pointing to a particular tag number, I need to edit the svn externals to point to a different tag number. I want to pass this new tag number as a parameter. How can I achieve this using powershell.

Answer 1

svn propset svn:externals "folder_name http://path_to_tag" .

Note the trailing dot.
