 NAME
      intro - introduction to system maintenance commands and application
      programs

 DESCRIPTION
      This section describes commands that are used chiefly for system
      maintenance and administration purposes.	The commands in this section
      should be used in conjunction with other sections of this manual, as
      well as the HP-UX System Administration manuals for your system.

    Command Syntax
      Unless otherwise noted, commands described in this section accept
      options and other arguments according to the following syntax:

	   name [ option ( s )] [ cmd_arg ( s )]

      where the elements are defined as follows:

	   name	     Name of an executable file.

	   option    One or more options can appear on a command line.	Each
		     takes one of the following forms:

			  -no_arg_letter
			       A single letter representing an option
			       without an argument.

			  -no_arg_letters
			       Two or more single-letter options combined
			       into a single command-line argument.

			  -arg_letter<>opt_arg
			       A single-letter option followed by a required
			       argument where:
				    arg_letter
					 is the single letter representing
					 an option that requires an
					 argument,
				    opt_arg
					 is an argument (character string)
					 satisfying the preceding
					 arg_letter,
				    <>	 represents optional white space.

	   cmd_arg   Path name (or other command argument) not beginning
		     with -, or - by itself indicating the standard input.
		     If two or more cmd_args appear, they must be separated
		     by white space.

 RETURN STATUS
      Upon termination, each command returns two bytes of status, one

      supplied by the system giving the cause for termination, and (in the
      case of ``normal'' termination) one supplied by the program (for
      descriptions, see wait(2) and exit(2)).  The system-supplied byte is 0
      for normal termination.  The byte provided by the program is
      customarily 0 for successful execution and non-zero to indicate errors
      or failure such as incorrect parameters in the command line, or bad or
      inaccessible data.  Values returned are usually called variously
      ``exit code'', ``exit status'', or ``return code'', and are described
      only where special conventions are involved.

 WARNINGS
      Some commands produce unexpected results when processing files
      containing null characters.  These commands often treat text input
      lines as strings and therefore become confused upon encountering a
      null character (the string terminator) within a line.

 SEE ALSO
      getopt(1), exit(2), wait(2), getopt(3C), hier(5), introduction(9).
