'yq' Notes

snap install yq

 

Output multiple fields:

$ yq '.interdotlink.name, .interdotlink.platform' r1-pop1.yaml 
r1-pop1
eos

 

Filter for fields with a specific value:

$ yq '.name, .platform|select(.platform == "eos")' *.yaml
r1-pop1
---
r2-pop1
---
r1-pop2
---
r2-pop2
---

 

Remove the YAML header:

$ yq -N '.name, .platform|select(.platform == "eos")' *.yaml
r1-pop1
r2-pop1
r1-pop2
r2-pop2

 

yq doesn't have if else support right now. One can chain select statements instead (to exclude lab devices and inactive devices):

$ yq -N '.[] | select(.name != "r*-lab") | select(.platform == "eos") | select(.status == "active") | .name'
