Setting multiline content generates |-

[AnderssonPeter]

Hi I'm using yq 4.28.1 the following way

cloud_init_content=$(./yq ".ssh_keys.${key_type}_private = \"$key_private\"" <<< $cloud_init_content) where $key_private is a openssh key so something like

-----BEGIN OPENSSH PRIVATE KEY-----
base64 string with
linebreaks
-----END OPENSSH PRIVATE KEY-----

But the output yml has

ssh_keys:
  rsa_private: |-
    -----BEGIN OPENSSH PRIVATE KEY-----
    .....

The problem here is that cloud-init doesn't like the - after the | is there any way to stop yq from generating it?
So what I'm after is rsa_private: | and not rsa_private: |-.

Found a temporary workaround config_content="${config_content//: |-$'\n'/: |$'\n'}" but I have never seen |- before so I'm not 100% sure if its a bug or not

Gday - take a look at this documentation here: https://mikefarah.gitbook.io/yq/operators/string-operators#string-blocks-bash-and-newlines

Basically the dash at the end of |- indicates that there is no new line at the end of the string (https://yaml-multiline.info/)
