parsing args in shell scripts in javascript

In JavaScript, parsing command line arguments in a shell script can be achieved using the "process.argv" property. Here's an example of how you can parse arguments in a JavaScript shell script:

index.tsx
// script.js

// Get the array of command line arguments
const args = process.argv.slice(2);

// Iterate over the arguments
args.forEach((arg, index) => {
  console.log(`Argument ${index + 1}: ${arg}`);
});
207 chars
10 lines

In this example, the process.argv property returns an array containing the command line arguments passed to the script. We use slice(2) to remove the first two default arguments ("node" and the script file path) and work with the rest of the arguments.

To test the script, you can run it using Node.js from the command line:

index.tsx
$ node script.js argument1 argument2 --option=value
52 chars
2 lines

The output will be:

index.tsx
Argument 1: argument1
Argument 2: argument2
Argument 3: --option=value
71 chars
4 lines

You can access each argument individually by indexing the args array.
