bos_help

BOS_HELP(8)						       AFS Command Reference						       BOS_HELP(8)

NAME
       bos_help - Displays help for bos commands

SYNOPSIS
       bos help [-topic <help string>+] [-help]

       bos h [-t <help string>+] [-h]

DESCRIPTION
       The bos help command displays the complete online help entry (short description and syntax statement) for each command operation code
       specified by the -topic argument. If the -topic argument is omitted, the output includes the first line (name and short description) of the
       online help entry for every bos command.

       To list every bos command whose name or short description includes a specified keyword, use the bos apropos command.

OPTIONS
       -topic <help string>+
	   Indicates each command for which to display the complete online help entry. Omit the bos part of the command name, providing only the
	   operation code (for example, specify status, not bos status). If this argument is omitted, the output briefly describes every bos
	   command.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT
       The online help entry for each bos command consists of the following two or three lines:

       o   The first line names the command and briefly describes its function.

       o   The second line lists aliases for the command, if any.

       o   The final line, which begins with the string "Usage", lists the command's options in the prescribed order. Online help entries use the
	   same symbols (for example, brackets) as the reference pages in this document.

EXAMPLES
       The following command displays the online help entry for the bos status command:

	  % bos help status
	  bos status: show server instance status
	  Usage: bos status -server <machine name> [-instance <server
	  process name>+] [-long] [-cell <cell name>] [-noauth]
	  [-localauth] [-help]
