Need help for get array keys to process after inside a bash loop

[cesarjorgemartinez]

Hi,

I have a yaml as follows:

data:
  item1: text1
  item2: text2
...

I need to get the key names, then:

yq eval '.data | keys' prueba2.yml 
- item1
- item2

But I need only the names, not the "- " part. Howto print as simple?:

item1
item2

I have yq version 4.16.2

Regards

By testing I have managed to remove it, but it seems quite long to remove "- ":

yq eval '.data | to_entries | .[].key'

The reason its showing the "- " is because it's printing an array, and thats the array format in yaml.
What you are trying to do is print all the values in the array, which you can do by 'splatting' or expanding the array like so:

yq '.data | keys| .[]' file.yaml
