Hi All,

I have a question

Can I use Reboot and Shutdown from Gambas?

I ask as I have a Program that take over my system and it stays in FULL screen (and the terminal only has a 32 keyboard attached)

I have a Menu with in my software that shows the following Menu

1. Exit PoS
2. Reboot PoS
3. Shutdown PoS


how do I reboot a system from with in Gambas?

I tried

Shell "Reboot now"

but it says Reboot not found (as it ha to be down as a SU User)

any recommendation is most welcomed.

i have commands reboot and shutdown in my system


Ps. not a lot of linux commands have capital letters in them

also be sure to not exit the application to soon before its got a chance to run the shutdown/reboot command as you can kill the process before it starts.

i have commands reboot and shutdown in my system

Code (gambas)

1. If sCommand = "Reboot" Then
2.   Shell "reboot"
3. Else If sCommand = "ShutDown" Then
4.   Shell "shutdown"
5. Endif
6.  

Ps. not a lot of linux commands have capital letters in them

also be sure to not exit the application to soon before its got a chance to run the shutdown/reboot command as you can kill the process before it starts.

I have this printed in the console window "/bin/sh: 1: reboot: not found

on my Debain machine I have to use SU before I can run reboot  is that why I am having issues with this command as well?

did you try Desktop.RunAsRoot()

or

or DBus..

My Desktop(ish) appication tries to shutdown/reboot in many ways.
Check out the Sysmenu file at
.src/SysMenu/fMenu.class · main · Bruce Steers / Desktop-ish · GitLab

It tries a few methods to shutdown/reboot/etc.

 debian puts reboot and shutdown in
/usr/sbin/reboot
/usr/sbin/shutdown

Being in sbin they are sudo only
if you move them to /usr/bin they will work

sudo mv /usr/sbin/reboot /usr/bin/reboot
sudo mv /usr/sbin/shutdown /usr/bin/shutdown

if you don't want to move the binaries then try dbus

dbus via shell..  (tested on debian11/MATE, needs dbus-send installed)


Gambas commands using gb.dbus component…

Code (gambas)

1. Shell "dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.Reboot boolean:true"
2.  

Code (gambas)

1. Shell "dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.PowerOff boolean:true"
2.  

Gambas commands using gb.dbus component…

Code (gambas)

1. DBus["system://org.freedesktop.login1"]["/org/freedesktop/login1", "org.freedesktop.login1.Manager"].Reboot(True)
2.  

Code (gambas)

1. DBus["system://org.freedesktop.login1"]["/org/freedesktop/login1", "org.freedesktop.login1.Manager"].PowerOff(True)
2.  

BruceSteers  you sir are a GENUINES.

also,,,,
if gnome exists..
DBus["session://org.gnome.SessionManager"]["/org/gnome/SessionManager", "org.gnome.SessionManager"].RequestShutdown()
DBus["session://org.gnome.SessionManager"]["/org/gnome/SessionManager", "org.gnome.SessionManager"].RequestReboot()

I try them all to try to make them work on any system. not all systems support freedesktop.login1 method …
this tries gnome.sessionmanager / kde.sessionmanager and freedesktop.login1 methods and also checks for cancelled request…
Note some shutdown methods will just shutdown while other will pop up the shutdown message window that offers options.


Download the Gambas DBus Explorer from the farm to see what DBus has to offer
Or better still use my version.
I modified the DBus explorer to copy almost usable command text when double clicking an item.
so if i doubleclick the gnome session manager CanShutdown item i get this copied to my clipboard..
DBus["session://org.gnome.SessionManager"]["/org/gnome/SessionManager", "org.gnome.SessionManager"].CanShutdown() ' As Boolean

EDIT: oops forgot to attach the explorer
