In these days I worked on a project checked-out from a Subversion repository. Due to particular working necessities, I had the need to completely “clean” this project deleting the SVN metadata and so, deleting all “.svn” folders located in the main project folder. Unfortunately, the project on which I worked on was very big and it had a complex directories structure, consequently, manually deleting all “.svn” folders from each directory and sub-directory of the main project folder was a very tedious thing. To solve this problem, I opened the Terminal in my cool Mac and I executed a simple script. Since this script could be useful to other persons, I decided to write a very small guide which describes how to do delete “.svn” hidden folders from a project directory.
