CPU(1) CPU(1)
NAME
cpu - connection to cpu server
SYNOPSIS
cpu [ -h server ] [ -c cmd args ... ]
DESCRIPTION
Cpu starts an rc(1) running on the server machine, or the
machine named in the $cpu environment variable if there is
no -h option. Rc's standard input, output, and error files
will be /dev/cons in the name space where the cpu command
was invoked. Normally, cpu is run in an 8½(1) window on a
terminal, so rc output goes to that window, and input comes
from the keyboard when that window is current. Rc's current
directory is the working directory of the cpu command
itself.
The name space for the new rc is an analogue of the name
space where the cpu command was invoked: it is the same
except for architecture-dependent bindings such as /bin and
the use of fast paths to file servers, if available.
If a -c argument is present, the remainder of the command
line is executed by rc on the server, and then cpu exits.
The name space is built by running /usr/$user/lib/profile
with the root of the invoking name space bound to /mnt/term.
The service environment variable is set to cpu; the cputype
and objtype environment variables reflect the server's
architecture.
FILES
The name space of the terminal side of the cpu command is
mounted on the CPU side on directory /mnt/term.

BUGS
Binds and mounts done after the terminal lib/profile is run
are not reflected in the new name space.
