cpo (create_process_only) create process without pads or windows
usage: cpo [ -n name ] pathname [args ...]
DESCRIPTION
The cpo command creates only a process, without associated pads or
windows. The three standard I/O streams are directed to /dev/null. If
this command appears in the node's DM boot startup script
`node_data/startup, the system assigns the new process the subject
identifier (SID) user.server.none.local_node, and the created process
continues to run regardless of whether anyone is logged in. This is
desirable for utilities like the prsvr (print_server) and netman, and
means that cpo is identical to cps in this context.
If cpo is issued in any other startup script or from the keyboard, the
SID of the new process is derived from whatever process invokes cpo, and
the created process terminates at logout.
ARGUMENTS
pathname (required)
Specify the file to be executed by the new process.
args... (optional)
Specify any arguments to be passed to the program
pathname. If any of these arguments contain explicit
blanks, enclose those arguments in quotation marks.
Default if omitted: no arguments passed
OPTIONS
-n name Assign process name name. If you omit this option, the
process is not named.
EXAMPLE
Run the alarm_server in a background process:
cpo /sys/alarm/alarm_server -disk 98 -bell1
