Bug Description

snap run does not work for me:

$ snap run postgresql-9-6 --shell
error: cannot find app "postgresql-9-6" in "postgresql-9-6"

This is quite possibly driver error, but the cli help fails to correctly document the command:

$ snap run --help
Usage:
  snap [OPTIONS] run [run-OPTIONS]

Run the given snap command with the right confinement and environment

Application Options:
      --version print the version and exit

Help Options:
  -h, --help Show this help message

[run command options]
          --shell run a shell instead of the command (useful for debugging)

Does `snap run --shell postgresql-9-6` work any differently?

snap run --shell postgresql-9-6.psql works. It seems I need the name of one of the snaps' apps, which makes sense as different apps can have different plugs.

So I think this bug is just cli documentation and maybe fixing the confusing error message in the edge case where there is no foo.foo app in the foo snap.

Ah, yes indeed, it needs an app. I also believe it needs options before positionals. You mention the error message should be improved, but it seems to me that it told you just that: "cannot find app[...]". How do you suggest that be improved?

I think the error message will be fine if the command line help is improved:

snap [OPTIONS] run [SNAP.APP] [ARGUMENTS]

snap run --shell $APP doesn't work for me, though.

$ snap run --shell postgresql-9-6
error: cannot find app "postgresql-9-6" in "postgresql-9-6"
$ snap --version

As it was pointed out in #1636229 by Michael Hall (mhall119) it should be "snap run --shell <command name>" not <snap name>.

For example:

$ snap run --shell postgresql93.psql

which works for me.
