nodeattrib(1) -- List or change confluent nodes attributes
=========================================================
## SYNOPSIS
`nodeattrib` `noderange` [ current | all ]
`nodeattrib` `noderange` [-b] [<nodeattribute>...]
`nodeattrib` `noderange` [<nodeattribute1=value1> <nodeattribute2=value2> ...]
`nodeattrib` `noderange` [-c] [<nodeattribute1> <nodeattribute2=value2> ...]
## DESCRIPTION
**nodeattrib** queries the confluent server to get information about nodes. In
the simplest form, it simply takes the given noderange(5) and lists the
matching nodes, one line at a time.
If a list of node attribute names are given, the value of those are also
displayed. If `-b` is specified, it will also display information on
how inherited and expression based attributes are defined. There is more
information on node attributes in nodeattributes(5) man page.
If `-c` is specified, this will set the nodeattribute to a null valid.
This is different from setting the value to an empty string.
## OPTIONS
* `-b`, `--blame`:
Annotate inherited and expression based attributes to show their base value.
* `-c`, `--clear`:
Clear given nodeattributes since '' is not the same as empty
## EXAMPLES
* Listing matching nodes of a simple noderange:
`# nodeattrib n1-n2`
`n1`: console.method: ipmi
`n1`: hardwaremanagement.manager: 172.30.3.1
`n2`: console.method: ipmi
`n2`: hardwaremanagement.manager: 172.30.3.2
* Getting an attribute of nodes matching a noderange:
`# nodeattrib n1,n2 hardwaremanagement.manager`
`n1: hardwaremanagement.manager: 172.30.3.1`
`n2: hardwaremanagement.manager: 172.30.3.2`
* Getting a group of attributes while determining what group defines them:
`# nodeattrib n1,n2 hardwaremanagement --blame`
`n1: hardwaremanagement.manager: 172.30.3.1`
`n1: hardwaremanagement.method: ipmi (inherited from group everything)`
`n1: hardwaremanagement.switch: r8e1`
`n1: hardwaremanagement.switchport: 14`
`n2: hardwaremanagement.manager: 172.30.3.2`
`n2: hardwaremanagement.method: ipmi (inherited from group everything)`
`n2: hardwaremanagement.switch: r8e1`
`n2: hardwaremanagement.switchport: 2`
* Listing matching nodes of a simple noderange that are set:
`# nodeattrib n1-n2 current`
`n1`: console.method: ipmi
`n1`: hardwaremanagement.manager: 172.30.3.1
`n2`: console.method: ipmi
`n2`: hardwaremanagement.manager: 172.30.3.2
* Change attribute on nodes of a simple noderange:
`# nodeattrib n1-n2 console.method=serial`
`n1`: console.method: serial
`n1`: hardwaremanagement.manager: 172.30.3.1
`n2`: console.method: serial
`n2`: hardwaremanagement.manager: 172.30.3.2
* Clear attribute on nodes of a simple noderange:
`# nodeattrib n1-n2 -c console.method`
`n1`: console.method:
`n1`: hardwaremanagement.manager: 172.30.3.1
`n2`: console.method:
`n2`: hardwaremanagement.manager: 172.30.3.2
