• Description

The dsh command runs commands concurrently on remote targets – nodes, hardware devices, or both. Targets can be selected from multiple contexts. A context is a target database that contains node and device definitions, such as the NIM database. The dsh command issues a remote shell command for each target specified. It returns output from all targets in a formatted manner to enable the command results from all nodes to be managed easily. The/usr/bin/rsh is the model for syntax and security and the dsh command is a DSM Distributed Shell Utility.
