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.

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
