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:

			     A single letter representing an option without an argument.

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

			     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 nor-
       mal  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.
