       clubak - format output from clush/pdsh-like output and more


       clubak [ OPTIONS ]


       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).


       clubak should be started with connected standard input.


              show clubak version number and exit

       -b, -c gather  nodes  with  same  output  (-c is provided for dshbak(1)

       -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

              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.


       An exit status of zero indicates success of the clubak command.


       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


       clush(1), nodeset(1), groups.conf(5).
