[^0-9] is being interpreted by your shell (probably bash) as a globbing
sequence that matches any files whose name is a single character that is
not a digit. If there are no matches, the glob is passed unaltered,
otherwise it is expanded. You probably meant to write "grep '[^0-9]'"
(note the single quotes!) to prevent shell expansion. It is ALWAYS good
practice to properly quote arguments.
