How to append element to first?

[kebhr]

For the following yaml, how do I append the element a before b?

sample.yml:

list:
  - b
  - c
  - d

expected result:

list:
  - a
  - b
  - c
  - d

I did it but it's not smart. Please comment if anyone knows smart solution.

yq '.list = ((.list | reverse) + "a" | reverse)' sample.yml

Try:

yq '.list = ["a"] + .list' sample.yaml
