try on your machine

The command you have provided uses the tool "yq" (short for "YAML Query") and its "write" subcommand to modify a YAML file.

Here is the breakdown of the command:

yq write --inplace ${filename-yaml} '${key}' '${value}'

yq: This is the executable command for the "yq" tool.
write: This is the subcommand used to modify a YAML file.
--inplace: This flag specifies that the changes should be made directly in the specified YAML file, rather than producing a new file with modifications.
${filename-yaml}: This is a placeholder for the name of the YAML file you want to modify. You'll need to replace ${filename-yaml} with the actual name of your YAML file, including the file extension.
'${key}': This is a placeholder for the specific key within the YAML file that you want to modify. You should replace '${key}' with the actual key you want to change.
'${value}': This is a placeholder for the new value that you want to set for the specified key. Replace '${value}' with the actual value you want to assign to the key.

In summary, this command uses "yq" to modify the specified YAML file by setting the value of a given key to a new value.
