Commands in the Azure ML yml files

Question

When reading the examples from Microsoft on azure ML CLI v2, they use the symbols: "|", ">", etc., in their yml files.

What do they mean, and where can I find explanations of possible syntax for the Azure CLI v2 engine?

Answer 1

| - This pipe symbol in YAML document is used for "Multiple line statements"

description: |
  # Azure Machine Learning "hello world" job

  This is a "hello world" job running in the cloud via Azure Machine Learning!

  ## Description

  Markdown is supported in the studio for job descriptions! You can edit the description there or via CLI.

in the above example, we need to write some multiple line description. So, we need to use "|" symbol

">" - This symbol is used to save some content directly to a specific location document.

command: echo "hello world" > ./outputs/helloworld.txt

In this above command, we need to post "hello world" to "helloworld.txt"

Check the below link for complete documentation regarding YAML files.

All these symbols are the YAML job commands which are used to accomplish a specific task through CLI.
