This is a super simple npm moudle 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.

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

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.
