collate(1) -- Organize text input by node
|
|
==============================
|
|
|
|
## SYNOPSIS
|
|
|
|
`<other command> | collate [-a] [-d] [-w] [-s] [-c] [-r]`
|
|
|
|
## DESCRIPTION
|
|
|
|
**collate** takes input in the form of <nodename>: <data> and groups
|
|
the output for each <nodename> together, and checks for identical data to further group nodes together.
|
|
Output groups are sorted in descending size such that the topmost group is the largest, and the
|
|
last output group is the smallest. In the event of equally sized output groups,
|
|
the groups are sorted alphanumerically by their header, and each header has
|
|
node and group names sorted alphanumerically.
|
|
|
|
## OPTIONS
|
|
|
|
* `-a`, `--abbreviate`:
|
|
Use confluent to attempt to shorten the noderange. This can help identify
|
|
when output differs along a telling group boundary. For example, if
|
|
output suggests a large number of nodes are unreachable, abbreviate
|
|
showing 'rack1' as being unreachable may make more obvious a possible cause.
|
|
|
|
* `-d`, `--diff`:
|
|
Express all but the most common result group in terms of diff from
|
|
the most common result group
|
|
|
|
* `-w`, `--watch`:
|
|
Update results dynamically as data becomes available, rather than
|
|
waiting for the command to fully complete.
|
|
|
|
* `-s`, `--skipcommon`:
|
|
Suppress printing of the most common result text group. This is used to
|
|
focus on stray output against a well known and expected result.
|
|
|
|
* `-c`, `--count`:
|
|
Print a count of the number of nodes in an output group under the
|
|
noderange.
|
|
|
|
* `-r`, `--reverse`:
|
|
Rather than starting with most common to least common, start with
|
|
the least common and print the most common last.
|
|
|
|
## EXAMPLES
|
|
* Organizing power state of multiple nodes:
|
|
`# nodepower n1-n12 | collate`
|
|
`====================================`
|
|
`n1,n2,n3,n4,n7,n8,n9,n10,n11,n12`
|
|
`====================================`
|
|
`on`
|
|
` `
|
|
`====================================`
|
|
`n5,n6`
|
|
`====================================`
|
|
`off`
|
|
|
|
* Using diff to detect distinct UEFI configuration
|
|
|
|
`# pasu n1-n4 show Processors|collate -d -s`
