How to make revert in SVN

1) Method through the ass((((((((((((((((((((((

%svn info f.txt
curr rev: 3
URL

%svn copy f.txt@2 f.txt__COPY
 %svn ci f.txt__COPY -m "Comment1"

%svn del f.txt
%svn ci f.txt -m "Comment2"

%svn copy f.txt__COPY f.txt
%svn ci f.txt -m "Comment3"

2) More beautyful method:
%svn merge -r HEAD:<REV> file.txt
%svn ci file.txt -m "Comment"

3) maybe svn mv --force -r <REV>
