Querying
--------

   To ask the user whether to execute a command on a single file, you
can use the `find' primary `-ok' instead of `-exec':

 - Action: -ok command ;
     Like `-exec' (Note: Single File), but ask the user first (on the
     standard input); if the response does not start with `y' or `Y',
     do not run the command, and return false.

   When processing multiple files with a single command, to query the
user you give `xargs' the following option.  When using this option, you
might find it useful to control the number of files processed per
invocation of the command (Note: Limiting Command Size).

`--interactive'
`-p'
     Prompt the user about whether to run each command line and read a
     line from the terminal.  Only run the command line if the response
     starts with `y' or `Y'.  Implies `-t'.
