   Usage: [[-s working_col_file|OS_name] | -w nodename{,nodename}] -c command

   Required Parameters:
         -s or -w and -c

   Optional Parameters:
         [-n]
         [-d] [-h] [-n] [-T] [-v]

   Where:
         -C
            Collapses output. Used with dshbak.
         -c specifies the command to run
            Required.
         -n
            No Parallel mode. By default the command is run on every node at the same time.
         -s
            Specify a working collective file OR specify an OS name. Use uname -s to specify
             a working collective file with that postfix. ie. /.gwcoll.AIX.
         -w nodename{,nodename}
            Default: ALL nodes

   Options that affect only how the script runs:
         -d
            Enable debug mode. Variable contents will be printed. May be specified more than once.
         -h
            Prints this help screen.
         -q
            quiet. Limits output to the essentials.
         -T
            Testing mode. NO actual work will be done.
         -v
            Verbose mode. May be specified more than once.

   Notes:
         One of -s or -w is required.
         Piping the output to dshbak -c will group like results together.
         Use -C with dshbak, or you will get no output.
         -c must be the last flag on the command line.

   Example execution statements:
         gdsh -s /.gwcoll.AIX -c date
         gdsh -s AIX -c date
         gdsh -C -s AIX -c date | dshbak -c
         gdsh -s all.Linux_HP-UX -c date
         gdsh -C -w unxn_sw,wpgux005 -c "date" | dshbak -c

gdsh -C -s HP-UX -c "/usr/bin/date" | dshbak -c
