1 8.1.4 Debug Options
1 -------------------
1 
1 The '-D' option makes 'find' produce diagnostic output.  Much of the
1 information is useful only for diagnosing problems, and so most people
1 will not find this option helpful.

1    The list of debug options should be comma separated.  Compatibility
1 of the debug options is not guaranteed between releases of findutils.
1 For a complete list of valid debug options, see the output of 'find -D
1 help'.  Valid debug options include:
1 'help'
1      Explain the debugging options.
1 'tree'
1      Show the expression tree in its original and optimised form.
1 'stat'
1      Print messages as files are examined with the stat and lstat system
1      calls.  The find program tries to minimise such calls.
1 'opt'
1      Prints diagnostic information relating to the optimisation of the
1      expression tree; see the '-O' option.
1 'rates'
1      Prints a summary indicating how often each predicate succeeded or
1      failed.
