node-cmd is a utility module for Node.js designed to simplify the process of running system commands or scripts. Whether you're executing a Python script, a shell command, or any other executable, node-cmd provides an easy-to-use API to handle command execution asynchronously.

• Supports running commands with both local file paths and URLs as arguments.
• Handles asynchronous operations seamlessly.
• Manages input and output streams efficiently.
• Provides error handling for command execution.

Here’s an example of how to use node-cmd to run a Python script:

const command = "python3";
const scriptPath = "/app/python-scripts/ngram_analysis.py";
const args = ["4", "/app/tmp/train_set.txt", "/path/to/test_set.txt"];

try {
  const result = await runCommand(command, scriptPath, args);
  console.log("Python script output:", result);
} catch (error) {
  console.error("Error running Python script:", error);
}

• command: The command to execute (e.g., python3, node, bash).
• src: The source file path or URL.
• args: Arguments to pass to the command. Can be a string or an array of strings.

Returns: A Promise that resolves to the command output (as a string) or true if there is no output. The Promise rejects with an error if the command execution fails.
