# 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.
