DO
DO
Execute an operating system command.
Format
DO [operating-system-command]
Command Qualifiers Defaults
/CLUSTER /NOCLUSTER
/NODE=node-list /NODE=default-node-list
/OUTPUT[=file-spec] /OUTPUT=stdout
Description
The DO command enables an operating system command to be executed from
RTR. By using the /NODE and /CLUSTER qualifiers the command can be executed
on one or more remote nodes. (Note that the SPAWN command does not have
this ability).
The DO command is only suitable for commands producing line oriented output,
use SPAWN if you want to execute a local operating system command that
produces screen oriented output (for example, the OpenVMS MONITOR SYSTEM
command, or screen mode editors).
Parameters
DCL-command
The operating system command that you want to execute.
Qualifiers
/CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither /NODE nor /CLUSTER is specified then the command is executed on the
nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT
command has been entered then the command is executed only on the node where
the command was issued.
Note: In environments that do not support clustering, use of the /CLUSTER
qualifier will cause the relevant command to be executed on the local node only.
/NODE[=node-list]
/NODE=default-node-list (D)
Specifies that the command is executed on all nodes specified in node-list . If
node-list is omitted then the command is executed only on the node where the
command was issued.
/OUTPUT[=file-spec]
/OUTPUT=stdout (D)
Specifies that the resulting information is written to the file file-spec . If
/OUTPUT or file-spec is omitted then the standard or default output is used.
