How to run a Bashtop or top after system rebooting, right after general menu (in Console) ?

Sergei_Shablovsky

Hi, pfSense Gurus!

How to run a bashtop / top after system rebooting, right after general menu (in Console).

I mean like You logging locally on Console Port or via Rack Terminal (Keyboard + Monitor) locally attached, and after successfully booting press "8" to loading Shell, and after loading "bashtop" or "top".

And additional question are "How to add extra one item (for example "Top") to general menu (in Console) for quickly launching "bashtop" or "top"?

May be solution are editing /etc/rc.initial ?

Thank You for help and suggestions! Have a nice sunny day!

Or using shellcmd option (described in https://docs.netgate.com/pfsense/en/latest/development/boot-commands.html#shellcmd-option) to start top?

Hi,

When you login, you're in front of the screen, right ?
As SSH access needs a cert password to be typed in, what's against an extra 8 + enter + top + enter ?

You tried it ?
top would start, find out it wasn't started using an interactive shell, so it quiet ... or refreshing the list it can't show, only eating system resources in the back ground.

You could just patch rc.initial. Can be a hidden option, like 101 say:

101)
	/usr/bin/top -aSH

It would get overwritten so you'd probably want to use an actual patch applied via the patches package.

Thank You for suggesting!

I am not sure that I clearly understanding You.

I just need after hardware “cool restart” (watchdog in UEFI, or in separate Hardware Monitoring pcb, or after power failure and reestablish) and bsd/pfSense start, AUTOMATICALLY going to console menu and start Bashtop item.
Just like this happened now, but AUTOMATICALLY go to certain menu item (in my case Bash).

Now I have 2 questions:

Why I need “hidden” option instead to creat normal menu item by editing original rc.initial file?

Please point me on User Manual that describe how to make the “patches package”. And how to make applying my custom “patches package(s)” each time after pfSense update (no matter what way from webgui or console)?

stephenw10

It doesn't have to be hidden you just have that option.

You need to create a diff file and then you can import that as a patch into the patches package.

I would create that by forking it on github and editing it. That will create the diff for you and give you a convenient commit url to import.
For example:
https://github.com/stephenw10/pfsense/commit/e66cd5949ee8a0c4d0c7c8d7c3bbfe1ed550da64

Ok, I understand how to create a patch from diff.

What a You suggest about how to automatically apply this “my patch” after each pfSense update ?

And back to topic, how to automatically start Bashtop/top/whatever from menu after pfSense loading? (Like local operator choose menu item in VGA console)

stephenw10

The patches packages has an option to 'auto apply' patches.

Adding those options to the rc.initial menu starts them from there. Just enter the menu number like any of the other entries.

Sorry my stupidness today, where in code I must insert to automatically start certain menu item ? (And I hope after Ctrl+C/Q/Esc, back to main rc.initial menu. Like, I start, let’s to say, “Ping host” and then back to rc.initial menu after exit from rc.initial.ping)

stephenw10

Ah, I haven't tried starting one of the options by default, without selecting something. I'm not sure how that would work if there wasn't actually a console attached.
But it's just a shell script, you can have it do whatever you can code it to.
