Reverting to old versions in SVN

If you want to revert everything to a previous version (ie revision 72):

svn merge -rHEAD:72 .

Note the “.” at the end!

If you want to revert all local changes (ie say go back to the head revision):

svn revert -R .

Again, note the “.” at the end.

To view the diff between two versions (ie what changed between revisions 72 and 73), use:

svn diff -r 72:73 file.java
