stdout

Only valid as a type for a CommandLineTool output with no outputBinding set.

The following

outputs:
  an_output_name:
    type: stdout

stdout: a_stdout_file

s equivalent to

outputs:
  an_output_name:
    type: File
    streamable: true
    outputBinding:
      glob: a_stdout_file

stdout: a_stdout_file

If there is no stdout name provided, a random filename will be created. For example, the following

outputs:
  an_output_name:
    type: stdout

s equivalent to

outputs:
  an_output_name:
    type: File
    streamable: true
    outputBinding:
      glob: random_stdout_filenameABCDEFG

stdout: random_stdout_filenameABCDEFG

If the CommandLineTool contains logically chained commands (e.g. echo a && echo b) stdout must include the output of every command.
