NAME
       intro  -	 introduction  to  system maintenance commands and application
       programs

DESCRIPTION
       This section describes commands that are	used chiefly for system	 main-
       tenance	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 op-
       tions 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:

			     A single letter representing an option without an
			     argument.

			     Two or more single-letter options
				    combined into a single command-line	 argu-
				    ment.

			     A single-letter option followed by	a required ar-
			     gument where:
				       arg_letter
					      is the single letter  represent-
					      ing  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 sup-
       plied by	the system giving the cause for	termination, and (in the  case
       of  ``normal''  termination)  one supplied by the program (for descrip-
       tions, 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 inaccessi-
       ble data.  Values returned are usually called variously ``exit  code'',
       ``exit  status'', or ``return code'', and are described only where spe-
       cial conventions	are involved.

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

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