CLUBAK(1) ClusterShell User Manual CLUBAK(1)NAMEclubak - format output from clush/pdsh-like output and moreSYNOPSISclubak [ OPTIONS ]DESCRIPTIONclubak 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).INVOCATIONclubak 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 outputsEXIT STATUSAn exit status of zero indicates success of the clubak command.EXAMPLES1. 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: 9SEE ALSOclush(1), nodeset(1), groups.conf(5).BUG REPORTSUse the following URL to submit a bug report or feedback: https://github.com/cea-hpc/clustershell/issuesAUTHORStephane Thiell, CEA DAM <stephane.thiell@cea.fr>COPYRIGHTCeCILL-C V1 1.6 2012-03-28 CLUBAK(1)
