How to detect that the case for a file path is correct on a case-insensitive file system
class File
# Does a case-sensitive check for file existence.
# Unlike the normal File.exists? method on OS X with its case-insensitive-by-default FS
def self.definitely_exists? path
folder = File.dirname path
filename = File.basename path
# Unlike Ruby IO, ls, and find -f, this technique will fail to locate the file if the case is wrong:
not %x( find "#{folder}" -name "#{filename}" ).empty?
end
