\fBDescription

.PP
|
||
|
|
The \fBxdshbak\fR command formats output from the \fBxdsh\fR
|
||
|
|
command. The \fBxdshbak\fR command takes lines in the following
|
||
|
|
format:
|
||
|
|
.sp
|
||
|
|
.nf
|
||
|
|
host_name: line of output from remote command
|
||
|
|
.fi
|
||
|
|
.sp
|
||
|
|
.PP
|
||
|
|
The \fBxdshbak\fR command formats the lines as follows and writes them
|
||
|
|
to standard output. Assume that the output from host_name3 and
|
||
|
|
host_name4 is identical, and the \fB-c\fR flag was specified:
|
||
|
|
.sp
|
||
|
|
.nf
|
||
|
|

|

|
|
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
|
||
|
|
\fBxdshbak\fR command writes "." for each 1000 lines of output
|
||
|
|
filtered.
|
||
|
|
.PP
|
||
|
|
If the \fB-x\fR flag is specified, the extra header lines that xdshbak normally displays for each node will be omitted, and \fBxdshbak\fR still sorts the output by node name for easier viewing:
|
||
|
|
.sp
