Let’s assume you’ve got a file (or a directory full of files, doesn’t matter) that you’ve been working on, and have committed it to the repository. Whoops, you’ve just overwritten something good with something bad. How to get the old one back?
I thought it would be a variation on the
svn revert command, but no. It’s
svn merge. This makes sense on some level, but not a lot of sense.It’s now too late to use
revert to get back to the previous state, since that only works on local changes, before you commit them. If the repository is at revision 439, and you checked in the right version of the file in revision 401, here’s the command you want:
svn merge -r439:401 ./myfile.txt
(Apparently you can also use
HEAD as the first revision number, but that didn’t work for me this morning.)
