Hi.
Code:
NAME
       pdsh - issue commands to groups of hosts in parallel


SYNOPSIS
       pdsh [options]... command


DESCRIPTION
       pdsh is a variant of the rsh(1) command. Unlike rsh(1), which runs
       commands on a single remote host, pdsh can run multiple remote commands
       in parallel. pdsh uses a "sliding window" (or fanout) of threads to
       conserve resources on the initiating host while allowing some
       connections to time out.

...

Good luck ... cheers, drl

DSHBAK(1)						      General Commands Manual							 DSHBAK(1)

NAME

       dshbak - format output from pdsh command

SYNOPSIS

       dshbak [OPTION]..

DESCRIPTION

       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.

OPTIONS

       -h     Display a summary of command line options.

       -c     Do not display identical output from nodes twice. Instead, print the list of nodes with matching output in the header block.

       -d DIR Write consolidated node output to separate files in output directory DIR. Any existing files will be overwritten.

       -f     With -d, force creation of specified DIR.

ORIGIN

       A rewrite of IBM dshbak(1) by Jim Garlick
       <garlick@llnl.gov> on LLNL's ASCI Blue-Pacific IBM SP system.
