3.1.4 What are the Cluster Aware Tools?
These utilities enable invoking common tasks on multiple nodes of the cluster from a single
point. The following is a brief description of the utilities. For detailed information, refer to the
man pages.
clsh - Runs batch commands on one, some or all nodes in the cluster.
clip - Runs interactive commands on one, some or all nodes in the cluster.
clcp - Copies files to one/some/all cluster nodes.
cluptime - Works like ruptime, only for all nodes in the cluster.
clps - Cluster-wide ps command.
clkill - Kills specified processes on specified nodes.
clinfo - Shows nodes and cluster information.
clpower - Utility to manage remote power operations on the cluster (ex.
turn the system power on and off, turn the locator lights on and off, enquire
the power status of compute nodes, etc.)
clsysfile - Utility to create and manage customizations to system files for
installation on compute nodes.
clgroup - Create a logical cluster group of nodes and propagate the group
information across all of the management tools in the cluster (including
PCC Clusterware and HP System Management tools)

3.1.5 clsh - Runs commands on one, some, or all nodes in the cluster.
The clsh program runs a remote shell to each host in the compute cluster with the specified
command. The command to run is echoed to the user's screen each time one is launched. A
