Hey! I'm new to WCL I'm trying to build new workflow that send curl command and save the output to file. Didn't succeeded any.

Can someone help me?

I will go ahead and add cwl tag to this post since that is what you are asking about. That tag is needed for cwl developers to notice this question. If this is not the case please let us know.

You can redirect the standard output of the command by using stdout keyword like below:

cwlVersion: v1.0
class: CommandLineTool
baseCommand: curl
arguments:
  - -L
inputs:
  url:
    type: string
    inputBinding:
      position: 1
outputs:
  type: stdout
stdout: out.txt

See the stdout section of the official CWL user guide here: https://www.commonwl.org/user_guide/05-stdout/index.html I recommend you to try the user guide from the first to the end, it's the best way to start writing CWL.

Alternatively, you can use the option -o to specify the file to write the output like this: https://github.com/suecharo/test-workflow/blob/master/tool/curl.cwl
