NAME
       sysenv - request system boot parameter

SYNOPSIS
       sysenv [boot-variable] ...

DESCRIPTION
       Sysenv  requests	 the value of one or more boot variables.  For example
       sysenv memory returns the list of free memory at system startup.	  Note
       that  some parameters have undergone "device translation" from a device
       name to a decimal device number.

       If no variable names are given then  the	 entire	 boot  environment  is
       listed.

SEE ALSO
       svrctl(2), monitor(8), boot(8).

DIAGNOSTICS
       Exit code 0 with the variable's value printed to standard output if all
       requested variables exist in the boot environment, exit code 1  on  any
       weird  error,  exit code 2 if one of the variables is not set, and exit
       code 3 if both kind of errors occurred.
