The argument vector is the list of arguments passed to the program when it is run. It is available as Bun.argv.
/icons/typescript.svgcli.ts
console.log(Bun.argv);
Running this file with arguments results in the following:
terminal
bun run cli.ts --flag1 --flag2 value

[ '/path/to/bun', '/path/to/cli.ts', '--flag1', '--flag2', 'value' ]
To parse argv into a more useful format, util.parseArgs would be helpful. Example:
/icons/typescript.svgcli.ts
import {parseArgs} from 'util';

const {values, positionals} = parseArgs({
	args: Bun.argv,
	options: {
		flag1: {
			type: 'boolean',
		},
		flag2: {
			type: 'string',
		},
	},
	strict: true,
	allowPositionals: true,
});

console.log(values);
console.log(positionals);
then it outputs
terminal
bun run cli.ts --flag1 --flag2 value

{
  flag1: true,
  flag2: "value",
}
[ "/path/to/bun", "/path/to/cli.ts" ]
