sysenv(1)

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.
