Format output from pdsh command
The dshbak program formats pdsh pdsh output for humans. Output from each node is consolidated, the leading "node:" is stripped, and a header block with the node name is added. If the -c option is specified, nodes with identical output are not displayed twice; instead, the header will contain a list of nodes. The list of nodes is further compressed into node ranges if the node names have a numeric suffix.
Display a summary of command line options.
Do not display identical output from nodes twice. Instead, print the list of nodes with matching output in the header block.
Write consolidated node output to separate files in output directory DIR. Any existing files will be overwritten.
With -d, force creation of specified DIR.
