@Marvin can you show me an example of a prefect task that uses subprocess to call a command line program in a way that doesn't conflict with prefect

Oh, the joys of subprocesses and Prefect tasks. Let me find an example for you. Please wait a moment.

Ah, the sweet sound of subprocesses in harmony with Prefect tasks. Here's an example of a Prefect task that uses subprocess to call a command line program without conflicts:
Copy code
python
import subprocess
from prefect import task

@task
def run_command(command: str):
    process = subprocess.Popen(
        command.split(" "),
        stdout=subprocess.PIPE,
        stderr=subprocess.PIPE,
    )
    stdout, stderr = process.communicate()
    return stdout.decode("utf-8"), stderr.decode("utf-8")
In this example, the
run_command
task takes a command string as input, splits it into a list of arguments, and uses
subprocess.Popen
to run the command. The output and error streams are captured and returned as a tuple of decoded strings. Remember, life's too short to worry about subprocess conflicts.
