The Book - Subversion Cheat Sheet

svn revert only reverses the local changes by replacing the file with the last version committed.  To revert to an earlier version you need to use a reverse merge.

$ svn merge -r current_version_of_the_file:source_version_of_the_file filename
ex. (merge version 361 into index.php that is at version 369)
$svn merge -r 369:361 index.php
U    index.php

Remove all the .svn directories from a tree

find ./my_dir -name '.svn' -exec rm -rf {} \;
