ENVSTORE(1)						    BSD General Commands Manual 					       ENVSTORE(1)

NAME

     envstore -- save and restore environment variables

SYNOPSIS

     envstore command [args ...]

DESCRIPTION

     envstore can save and restore environment variables, thus transferring them between different shells.

     command must be one of

     clear
	 Forget all stored variables

     eval
	 Produce shell code for evaluation, restoring all saved variables

     list
	 List saved variables in better readable format

     save variable [value]
	 Save variable either with its current shell value or with value

     rm variable
	 Remove variable from store

     Note: Only the first character of command is checked, so envstore e instead of envstore eval, envstore c for envstore clear, etc., are also
     valid.

ENVIRONMENT

     ENVSTORE_FILE  The file in which the environment parameters are stored, /tmp/envstore-EUID by default,

LIMITATIONS

     Variable names or values must not contain null bytes or newlines.

     Due to limitations imposed by most shells, it is not possible to save parameters containing more than one consecutive whitespace.	envstore
     will save and display them correctly, but unless you do IFS trickery, your shell will not be able to load them.

     The current maximum length (in bytes) is 255 bytes for the variable name and 1023 bytes for its content.

NAME

       consvar - Manipulate system firmware console environment variables

SYNOPSIS

       /sbin/consvar [-v] [-nc] -g  -s	-l  -a	-d  [variable] [value]

OPTIONS

       Verbose mode.  Prints out the system IDs used by firmware, the current firmware revision, and information about the process.  Get the value
       of the specified console environment variable.  Set the value of the specified console environment variable.  List the values of all  vari-
       ables  supported by this platform that are not disabled.  This is similar to the show SRM console command.  Save the values of all environ-
       ment variables to non-volatile storage. Setting a variable with the -s option only updates the in-memory copy of console environment  vari-
       ables.	The  save process could take a long time on some platforms, so it is recommended that the variables are saved after all set opera-
       tions have been performed.  List the system and exception database information.	Do not perform value conversion.  Variables  that  contain
       device  information  have an underlying console bootstring format.  If this option is used, consvar does not convert between the Tru64 UNIX
       names for these devices, but accepts and displays the raw values.  The same goes for integer values which are converted between strings and
       hexadecimal values.

DESCRIPTION

       Use the consvar command to get, set, list, and save console environment variables available on SRM system firmware.  Some firmware versions
       on some platforms do not comply with the Alpha SRM when dealing with certain variables, or operations.  To ensure UNIX  functionality  with
       such firmware, an exception database is consulted and these operations are disabled. By default, consvar accepts and displays device values
       with Tru64 UNIX device names, or their device special file names. The raw console bootstrings can be used by providing the -nc option.  For
       information regarding the console environment variables, please refer to the Alpha System Reference Manual.

RETURN VALUES

       Success.  Failure.

EXAMPLES

       To show the values of all available console variables, enter: % consvar -l To get the value of the booted_dev variable, enter: % consvar -g
       booted_dev

	      A message similar to the following will be displayed: booted_dev = disk0 To set the value of boot_dev, enter the device name of  the
	      required boot device: % consvar -s boot_dev disk0

	      To  save the values of the variables across system resets, enter: % consvar -a If an operation fails, you can find out if it is dis-
	      abled by using the -v option.  For example, to see if the bootdef_dev variable is disabled, enter: % consvar -v -g  bootdef_dev  The
	      exception  database  can	be  printed  out  along  with the status of the current platform's console variable support by entering: %
	      consvar -v -d

FILES

       Specifies the command path.  Exception database.
