How to remove a certian element in an array

[AristoChen]

Hi, I am quite new to yq, and I have tried to google and search the discussions here for a while, still not able to get the expected ressult

Here is the test.yaml that I have

build-packages:
  - bc
  - bison
  - build-essential
  - on amd64:
    - gcc-aarch64-linux-gnu
    - gcc-or1k-elf

I would like to remove the gcc-or1k-elf, and the expected outcome should be

build-packages:
  - bc
  - bison
  - build-essential
  - on amd64:
    - gcc-aarch64-linux-gnu

Thanks in advance for any help!

Have you tried something like this ?

yq eval 'del(.["build-packages"][] | select(. == "gcc-or1k-elf"))' test.yaml

Hi @SamirPS ,

Thanks for your reply!

yq eval 'del(.["build-packages"][] | select(. == "gcc-or1k-elf"))' test.yaml

yes, I have tried that before, however it doesn't work

Easiest way to do it is to recursively search for that value and delete it - though this will delete other items matching that value:

yq  'del(.. | select(. == "gcc-or1k-elf"))' file.yaml

Otherwise, if you want to snipe it, then you have to put in the full path - which in this case is quite deep as there are a couple of arrays of maps:

yq eval 'del(.["build-packages"][] | select(has("on amd64")) | .[][] | select(. == "gcc-or1k-elf"))' file.yaml

Thanks @mikefarah ! that works!
