cmexec(1m)cmexec(1m)NAMEcmexec - Execute process on a remote Serviceguard node.
SYNOPSIScmexec node_name [-o outfile] [-t timeout]
{[command] | [-k cmd_label]}
DESCRIPTIONcmexec will execute a process on a remote Serviceguard node and return
any output or return value.
cmexec is limited in several ways. cmexec 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
the remote node. For more information on Serviceguard access control
policies, see the manual, Managing Serviceguard.
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.
Input via stdin is not supported.
Killing the cmexec process does not stop the remote execution of the
command. cmexec should not be used on any command which may hang with‐
out specifying a timeout value.
Options And Arguments
cmexec supports the following arguments:
-o outfile
Write output to the specified file instead of stdout.
-t timeout
Kill the executed command if it does not exit within the
specified timeout (in seconds)
node_name

command

-k cmd_label

RETURN VALUEcmexec returns the exit value for the remote command or 1 if there was
an error communicating with the Serviceguard node.
EXAMPLES
Execute an 'ls' in a remote directory.
cmexec node ls /tmp
