Parallel execution of commands

[marcosh]

If I understand correctly, currently it is possible to execute commands just one after the other.

Would it be interesting/possible to configure certain commands to run in parallel?

For example, I could have four commands a, b, c and d and I would like to run a, then b and c in parallel and only after they both complete, run d

That's an interesting proposition. I'm not sure what it would look like to issue a command like that - what do you suggest the semantics to be?

Also - I'm pretty tight on time these days so I probably will not be able to get to this in a timely manner, but I'll still be available for PR reviews and hackage administration.

this might be something I'd be interested to work in, so I could try to set up a PR.

I imagine parallel commands could work in two ways:

• their output is intertwined, which could make them hard to read
• only the output of the first is shown in real time, and only after it finishes the output of the others is returned

I would probably opt for the second option, but maybe it could be configurable
