Multiple commands is not supported in Procfile

[jxltom]

command_a; command_b or command_a && command_b format command in Procfile is not supported.

This is because eval echo "$@ in exec setuidgid "$unprivileged_user" $(eval echo "$@")

herokuish/include/procfile.bash

Line 55 in 1bf5365

exec setuidgid "$unprivileged_user" $(eval echo "$@")

will strip the multiple commands

[jxltom]

Currently I can only run multiple command by web $(command_a; command_b)

[michaelshobbs]

That is correct. I also use a Makefile to achieve executing multiple commands where absolutely necessary.

[jxltom]

@michaelshobbs But in heroku, web: command_a; command_b is supported. Why not herokuish support multiple commands like that? Considering herokuish is trying to emulating heroku, it will be nice to have same behaviour.

Because its hard to do it and not a common pattern. I would actually say that such a Procfile is wrong, but since there isn't a Procfile standard out there, shrug.

If you would like to submit a pull request to change this (with tests!) feel more than free to do so. I'd be happy to review :)

@josegonzalez

OK. Thanks for clarifying my doubt.

I'd like to note with the backref above, that this is expected behavior in a lot of apps targeting heroku out of the box, like for instance https://github.com/tootsuite/mastodon

If you'd like to make a pull request implementing this functionality, that would be great. Otherwise, I don't think it's worth the effort.
