SYSENV(1)                 Minix Programmer's Manual                  SYSENV(1)


NAME
     sysenv - request system boot parameter

SYNOPSIS
     sysenv boot-variable

DESCRIPTION
     Sysenv requests the value of a boot variable.  For example sysenv memsize
     returns  the  number  of  kilobytes  of  "normal" memory.  Note that some
     parameters have undergone "device translation" from a device  name  to  a
     decimal device number.

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

DIAGNOSTICS
     Exit code 0 with the variable's value printed to standard output  if  the
     variable  exists  in the boot environment, exit code 2 if the variable is
     not set, and exit code 1 with an appropriate error message for  any  kind
     of error.

BUGS
     Can't be used to list the entire environment.
