B<xdshbak> - Formats the output of the B<xdsh> command.
|
||
|
|
|
||
|
|
=head1 B<SYNOPSIS>
|
||
|
|
|
||
|
|
B<xdshbak> [B<-c> | B<-x>]
|
||
|
|
|
||
|
|
=head1 B<DESCRIPTION>
|
||
|
|
|
||
|
|
The B<xdshbak> command formats output from the B<xdsh> command. The B<xdshbak>
|
||
|
|
command takes, as input, lines in the following format:
|
||
|
|
|
||
|
|
host_name: line of output from remote command
|
||
|
|
|
||
|
|
The B<xdshbak> command formats the lines as follows and writes them to
|
||
|
|
standard output. Assume that the output from node3 and node4
|
||
|
|
is identical, and the B<-c> (collapse) flag was specified:
|
||
|
|
|
||
|
|
HOSTS --------------------------------------------------------
|
||
|
|
node1
|
||
|
|
--------------------------------------------------------------
|
||
|
|
.
|
||
|
|
.
|
||
|
|
lines from xdsh for node1 with hostnames stripped off
|
||
|
|
.
|
||
|
|
.
|
||
|
|
HOSTS --------------------------------------------------------
|
||
|
|
node2
|
||
|
|
--------------------------------------------------------------
|
||
|
|
.
|
||
|
|
.
|
||
|
|
lines from xdsh for node2 with hostnames stripped off
|
||
|
|
.
|
||
|
|
.
|
||
|
|
HOSTS --------------------------------------------------------
|
||
|
|
node3, node4
|
||
|
|
--------------------------------------------------------------
|
||
|
|
.
|
||
|
|
.
|
||
|
|
lines from xdsh for node 3 with hostnames stripped off
|
||
|
|
.
|
||
|
|
.
|
||
|
|
|
||
|
|
When output is displayed from more than one node in collapsed form, the
|
||
|
|
host names are displayed alphabetically. When output is not collapsed,
|
||
|
|
output is displayed sorted alphabetically by host name. The B<xdshbak>
|
||
|
|
command writes "." for each 1000 lines of output processed (to show progress),
|
||
|
|
since it won't display the output until it has processed all of it.
|
||
|
|
|
||
|
|
If the B<-x> flag is specified, the extra header lines that xdshbak nor-
|
||
|
|
mally displays for each node will be omitted, and the hostname at the beginning
|
||
|
|
of each line is not stripped off, but B<xdshbak> still sorts
|
||
|
|
the output by hostname for easier viewing:
|
||
|
|
|
||
|
|
node1: lines from xdsh for node1
|
||
|
|
.
|
||
|
|
.
|
||
|
|
node2: lines from xdsh for node2
|
||
|
|
.
|
||
|
|
.
|
||
|
|
|
||
|
|
B<Standard> B<Error>
|
||
|
|
|
||
|
|
When the B<xdshbak> filter is used and standard error messages are gener-
|
||
|
|
ated, all error messages on standard error appear before all standard
|
||
|
|
output messages. This is true with and without the B<-c> flag.

|

|
|
|
||
|
|
=item B<-c>
|
||
|
|
|
||
|
|
If the output from multiple nodes is identical it will be collapsed
|
||
|
|
and displayed only once.
|
||
|
|
|
||
|
|
=item B<-x>
|
||
|
|
|
||
|
|
Omit the extra header lines that xdshbak normally displays for
|
||
|
|
each node. This provides
|
||
|
|
more compact output, but xdshbak still sorts the output by
|
||
|
|
node name for easier viewing.
|
||
|
|
This option should not be used with B<-c>.
