Run a dynamic number of bash commands in parallel, collect all exit codes.

You can interact with the shell script directly. Using NPM, install this project.* Then reference the script with: ./node_modules/generic-subshell/lib/run.sh. Or just copy and paste the script in your project and make it your own :)
-
There is a Node.js interface - pass the Node.js interface an array of commands, and this library will return with a reference to the child process.
import * as gs from 'generic-subshell'; // using es5 it's: const gs = require('generic-subshell'); const commands = [ 'echo "foo"', 'echo "baz"', 'echo "bar"' ]; const k = gs.run(commands); // returns a child process k.once('exit', function(code){ // if code is 0, all subshells exited with code 0 // if code is 1, at least one subshell exited with an non-zero code });
npm install generic-subshell --save
