I'm surprised I haven't been able to find an answer to this after googling for half-an-hour.
My filename is Default-LandscapeRight@2x.png but it cuts of the filename at the '@' sign (can't find file 'Default-LandscapeRight') within the OSX Terminal when entering a command. I tried escaping it with a slash in front, i tried putting the whole filename in single quotes but it does not do the trick.
Edit: I'm trying to add a file using SVN (Subversion). svn add Default-LandscapeRight@2x.png
