  ? is a wildcard in most UNIX shells. Operators prefer not to have to
  escape characters in routine commands.

  What if a capture file contains the character '?' ?

  To list capture files in a directory, why not use the appropriate
  combination of ls, find, and file (or whichever the equivalent is in
  Windows), instead of tcpdump?
