With the iPhone 4’s high-resolution screen, designers need to create two sets of art; the guidelines are to name the files like so: SomeCoolImage.png and SomeCoolImage@2x.png. Unfortunately, if you try to add these files to an SVN repository, the @ symbol throws them off:
$ svn add Icon\@2x~iphone.png svn: warning: 'Icon' not found
The fix, thanks to the subversion_users Google Group, is to add another @ to the end of the filename, like so:
$ svn add ./Icon\@2x~iphone.png@ A (bin) Icon@2x~iphone.png
If you’d like to do this for all of your high-resolution art in a folder, here’s a tiny Bash command for the task:
for x in `ls *\@*`; do svn add $x\@; done
