  expression is specified then defaults to -print\.
  
  The following primary expressions are recognised:
    -name pattern
    -iname pattern
      Evaluates as true if the basename of the file matches the
      pattern using standard file system globbing\.
      If -iname is used then the match is case insensitive\.
  
    -print
    -print0
      Always evaluates to true. Causes the current pathname to be
      written to standard output followed by a newline. If the -print0
      expression is used then an ASCII NULL character is appended rather
      than a newline.
  
  The following operators are recognised:
    expression -a expression
    expression -and expression
    expression expression
      Logical AND operator for joining two expressions\. Returns
      true if both child expressions return true\. Implied by the
      juxtaposition of two expressions and so does not need to be
      explicitly specified\. The second expression will not be
      applied if the first fails\.
