CPO (CREATE_PROCESS_ONLY) -- Create process without pads or windows.
usage: cpo pathname [-n name] [args ...]
FORMAT
CPO pathname [options]
The CPO command creates only a process, without associated pads or windows.
The four 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 will continue to run
regardless of whether or not any one 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. (This is only effective at version 6.0 and
later.)
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 will terminate at logout.
ARGUMENTS
pathname
(required) Specify file to be executed by the new process.
OPTIONS
-N name Assign process name 'name'. If omitted, the process is not
named.
args . . . Specify any arguments to be passed to the program
'pathname'. If any of these arguments contain explicit
blanks, enclose those arguments in quotation marks.
