I found it s simple to do this via the svn cat command so that you don t even have to specify a revision   svn cat mydir myfile  gt  mydir myfile   This probably won t role back the inode  metadata  data such as timestamps

For a single file  you could do   svn export -r  lt REV gt  svn   host path to file on repos file ext  You could do svn revert  lt file gt  but that will only restore the last working copy

surprised no one mentioned this  without finding out the revision number you could write this  if you just committed something that you want to revert  this wont work if you changed some other file and the target file is not the last changed file  svn merge -r HEAD PREV file

An alternate option for a single file is to  replace  the current version of the file with the older revision   svn rm file ext svn cp svn   host path to file on repo file ext  lt REV gt  file ext svn ci   This has the added feature that the unwanted changes do not show up in the log for this file  i e  svn log file ext

If it s only a couple of files  and if you re using Tortoise SVN  you can use the following approach    Right click on your source file  and select  TortoiseSVN  -   Show log   Right click on a revision in the log  and select  Save revision to      Let the old revision overwrite your current file  Commit the overwritten source file

Just adding on to  Mitch Dempsy answer since I don t have enough rep to comment yet   svn export -r  lt REV gt  svn   host path to file on repos --force   Adding the --force will overwrite the local copy with the export and then you can do an svn commit to push it to the repository

So far all answers here seem to have significant downsides  are complicated  need to find the repo URI  or they don t do what the question probably asked for  How to get the Repo in a working state again with that older version of the file   svn merge -r head  revision-number-to-revert-to   file-path  is IMO the cleanest and simplest way to do this  Please note that bringing back a deleted file does not seem to work this way 1   See also the following question  Better way to revert to a previous SVN revision of a file    1  For that you want svn cp -r  rev-number   repo-URI file-path   rev-number   repo-URI file-path   amp  amp  svn up  see also What is the correct way to restore a deleted file from SVN

The best way is to   svn merge -c -RevisionToUndo   trunk   This will undo all files of the revision than simply revert those file you don t like to undo  Don t forget the dash  -  as prefix for the revision   svn revert File1 File2   Now commit the changes back
