[Proposal] mix run --recursive

[Michał Muskała]

Hello everybody,

Today I encountered an interesting problem. We're doing seeding for our applications with a custom mix alias: "run priv/repo/seeds/**/*", which works great. The problem is we're using umbrella applications with multiple ecto repos, so each application has it's own seeds. You can imagine how annoying it is having to run seeds for each application separately.

I would like to propose adding --recursive flag to the run task, that would make it apply it's arguments in each application separately. This would allow creating an alias in the top-level mix.exs to run seeds in each application.

What do you think?

Michał.

I am -1 because you can solve it with aliases OR by using "mix cmd mix run priv/repo/seeds.ex" (which runs a command on all children apps).

I cannot solve this with an alias - I can't create a recursive alias in the root of umbrella.

I didn't knew mix cmd existed. It indeed covers this use case. Thank you.

I have solved a similar problem with a little bit of shell hackery. We also have *a lot* of seed scripts.

What I did is something in the lines of:

```
for f in $(find $seedDirs -name seeds*.exs); do cd $somewhere && mix run $f; done
```

I don't have the exact command right now, but its not far away from that.
