This command mainly have two purposes.
One is compare the base version and nearly change in local.
(The base version is the version which we change on this.)
command : svn diff
( the same operation like compare with-->base Revision)
The second use is to find out what has changed between two revisions using: svn diff -r revision1:revision2 FILENAME. For example: svn diff -r 168:169 index.xml will output a diff showing the changes between revisions 168 and 169 of index.xml.
