Suppress "Welcome Screen" when using --silent

[ghost]

What's going wrong?

The Welcome Screen (the big ASCII PM2) should respect the --silent option.

I use pm2 to launch node processes inside docker containers. When a new container is created then pm2 prints the welcome screen in the log. Therefore the first 35 lines of each container log look like this:

container.service-foo |
container.service-foo |                         -------------

It would be nice if the Welcome Screen would respect the --silent option and not show itself in that case.

How could we reproduce this issue?

Start pm2 with the option "--silent" on a host where the folder ~/.pm2 does not exist yet.

Tested on pm2 2.4.6

As a workaround I added pm2 status > /dev/null to my startup file to "eat" the welcome screen.

I’d appreciate if there was a way to silence the banner only (--no-banner or something). I’m in the same situation: lots of Docker container logs starting with the banner. But I’m actually interested in the regular output.

To be honest, as cool as the ASCII logo is, it’s pretty annoying in practice.

Edit: I see now that this is essentially #1658, though that doesn’t offer a solution.

PM2_DISCRETE_MODE=true does the job but it probably hides other things as well which might not be desired. We need a separate flag to just hide the banner.
