How to recover files that have accidentally been deleted with 'svn delete'.
To recover a file from svn that you deleted from your local repository, it’s first necessary to get the proper name of the file, and the revision of the repository it last existed in. To do that (assuming you don’t know, because if you do you have bigger issues), you go to the directory it was in (or as close as you can get to the directory it was in) and run:
svn log --verbose
You should be able to find the file you’re looking for and the revision you need in the output of that command. Assuming your file’s name is ‘file.txt’ and it was in revision 250, you run the following to recover it:
svn up -r 250 file.txt
