Parallel Shell

This is a super simple npm module to run shell commands in parallel. All processes will share the same stdout/stderr, and if any command exits with a non-zero exit status, the rest are stopped and the exit code carries through.

Install

Simply run the following to install this to your project:

npm i --save-dev parallelshell

Or, to install it globally, run:

npm i -g parallelshell

Usage

To use the command, simply call it with a set of strings - which correspond to shell arguments, for example:

parallelshell "echo 1" "echo 2" "echo 3"

This will execute the commands echo 1 echo 2 and echo 3 simultaneously.

Note that on Windows, you need to use double-quotes to avoid confusing the argument parser.

Available options:

-h, --help         output usage information
-v, --verbose      verbose logging
-w, --wait         will not close silbling processes on error
