People,

On F25 x86_64 as user "fedora" with default environment I get:

grep Cock application.html.erb

   Provider for the National Disability Insurance Trial Site in Kwinana/
Cockburn</a>

grep Cock *

   grep: *: No such file or directory

This behaviour generally means that the file is in a directory that is readable but not searchable.  But root does not have that restriction and can expand the pattern.
