[TIP] Processing YAML files with yq

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.

Example YAML-File:

Code:
--- !ruby/object:Puppet::Node::Facts
  values:
    processors:
      models:
        - "Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz"
      count: 1
      physicalcount: 1
    kernel: Linux
    architecture: x86_64
    hardwaremodel: x86_64
    operatingsystem: CentOS
    os:
      name: CentOS
      family: RedHat
      release:
        major: "6"
        minor: "10"
        full: "6.10"
    processor0: "Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz"

yq - Usage:

Code:
# Command
yq -r .values.os.family data.yaml

# Output
RedHat

It's already available via repository in newer versions of major linux distributions

Return the CPU set describing the locality of the MIC device whose index is idx. Topology topology and device index idx must match the local machine. I/O devices detection is not needed in the topology. The function only returns the locality of the device. If more information about the device is needed, OS objects should be used instead, see hwloc_intel_mic_get_device_osdev_by_index(). This function is currently only implemented in a meaningful way for Linux; other systems will simply get a full cpuset. static inline hwloc_obj_t hwloc_intel_mic_get_device_osdev_by_index (hwloc_topology_ttopology, unsignedidx) [static] Get the hwloc OS device object corresponding to the MIC device for the given index. Return the OS device object describing the MIC device whose index is idx. Return NULL if there is none. The topology topology does not necessarily have to match the current machine. For instance the topology may be an XML import of a remote host. I/O devices detection must be enabled in the topology. Note: The corresponding PCI device object can be obtained by looking at the OS device parent object. Author Generated automatically by Doxygen for Hardware Locality (hwloc) from the source code.
