Modifying subversion file permissions

I saw this question but it does not help me. I checked in a file without the executable permission and now, every time I branch or checkout, the file is not executable.

Some other files are indeed saved as executable. I'm guessing that it's because they had the executable bit during first check in--at least that's what my testing leads me to believe.

Does anyone know of a better way to modify (or even at least view) the permissions that subversion has for开发者_如何学Go a file or folder?

Use svn propset as follows:

svn propset svn:executable ON executable_file

Then perform svn commit.
