cmdo(1m)cmdo(1m)NAMEcmdo - Execute process on multiple remote Serviceguard nodes.
SYNOPSIScmdo [[-n node_name]...] [-t timeout] command
DESCRIPTIONcmdo will execute a process on a multiple remote Serviceguard nodes and
return any output or return value.
cmdo is limited in several ways. cmdo is best suited for situations
where other remote execution facilities are not available. For a more
full featured tool for remote execution within a cluster, see cexec(1m)
provided by Distributed Systems Administration Utilities.
To use this command, the local user must have the root access role on
each of the involved nodes. For more information on Serviceguard access
control policies, see the manual, Managing Serviceguard.
To use the cmdo command without specifying -n options, the local node
must be configured into a Serviceguard cluster. If no -n options are
specified, the command will be executed on all available nodes in the
The command will be executed in an environment which matches the local
node. All environment variables defined locally will be available on
the remote node.
Output from stderr and stdout for the remote process will be combined
and delivered in one transmission. This command should not be used for
interactive commands or commands which will return large quantities of
output. Output from each node will be displayed sequentially as the
operation is executed on each remote node.
Input via stdin is not supported.
Killing the cmdo process does not stop any remote executions of the
command. cmdo should not be used on any command which may hang without
specifying a timeout value.
Options And Arguments

RETURN VALUEcmdo returns the following values:
