There are revision keywords like HEAD which references the latest revision and PREV which references the last changed revision of the target. E.g: SVN diff -rHEAD:PREV target.file will show the changes between the last changed revision for that file and the latest revision, which is effectively the change introduced by that last revision.

The diff should be sent to WinMerge for display. In the WinMerge docs (http://manual.winmerge.org/Version_control.html) they suggest to use this command line: svn diff --diff-cmd "<path to WinMerge executable>" -x "-dl -dr" <file to check> But when I try this in a WC on a file that is part of the project nothing at all happens: svn diff --diff-cmd "C:\Programs\WinMerge\WinMergeU.exe" -x "-dl -dr" espconfig.cpp I suspect that the svn diff needs something more to work correctly, the above command might only work with *local* uncommitted changes? In SVNBook is shown the diff command as: svn -diff -r 2:3 <filename> where 2 and 3 are the revisions to compare. But my problem is that the revisions where the file actually changed last is not known, so how can I put the correct number into the command? There is also the --change parameter to svn diff, but the same problem reappears: how to find out the revision where this particular file changed in the past? I am running Svn 1.9.7 command line client on Windows 7 X64. I cannot install Tortoise because my Windows Explorer plug-in handler is already filled to capacity... -- Bo Berglund Developer in Sweden
