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.

CLUBAK(1) ClusterShell User Manual CLUBAK(1)NAME
clubak - format output from clush/pdsh-like output and more
SYNOPSIS
clubak [ OPTIONS ]
DESCRIPTION
clubak formats text from standard input containing lines of the form "node:output". It is fully backward compatible with dshbak(1) but
provides additonal features. For instance, clubak always displays its results sorted by node/nodeset.
You do not need to use clubak when using clush(1) as all output formatting features are already included in. It is provided for other
usages, like post-processing results of the form "node:output".
Like clush(1), clubak uses the ClusterShell.MsgTree module of the ClusterShell library (see pydoc ClusterShell.MsgTree).
INVOCATION
clubak should be started with connected standard input.
OPTIONS --version
show clubak version number and exit
-b, -c gather nodes with same output (-c is provided for dshbak(1) compatibility)
-d, --debug
output more messages for debugging purpose
-L disable header block and order output by nodes
-r, --regroup
fold nodeset using node groups
-s GROUPSOURCE, --groupsource=GROUPSOURCE
optional groups.conf(5) group source to use
-G, --groupbase
do not display group source prefix (always @groupname)
-S SEPARATOR, --separator=SEPARATOR
node / line content separator string (default: :)
-F, --fast
faster but memory hungry mode (preload all messages per node)
-T, --tree
message tree trace mode; switch to enable ClusterShell.MsgTree trace mode, all keys/nodes being kept for each message element of the
tree, thus allowing special output gathering
--color=WHENCOLOR
whether to use ANSI colors to surround node or nodeset prefix/header with escape sequences to display them in color on the terminal.
WHENCOLOR is never, always or auto (which use color if standard output refers to a terminal). Color is set to [34m (blue foreground
text) and cannot be modified.
--diff show diff between gathered outputs
EXIT STATUS
An exit status of zero indicates success of the clubak command.
EXAMPLES
1. clubak can be used to gather some recorded clush(1) results:
Record clush(1) results in a file:
# clush -w node[1-7] uname -r >/tmp/clush_output
# clush -w node[32-159] uname -r >>/tmp/clush_output
Display file gathered results (in line-mode):
# clubak -bL </tmp/clush_output
2. Another example, iterate over node* text files in current directory and gather characters count for all of them:
# find -name "node*" -exec wc -c {} ; | awk '{ gsub("./","",$2); print $2": "$1 }' | clubak -bL
node[1,3]: 7
node2: 9
