When Fuchsia is booted and displays the $ prompt in the shell, you can now run
components. In Fuchsia, components are the basic
unit of executable software.
To run components on your Fuchsia device, see Run an example component.
Run shell commands
To shutdown or reboot Fuchsia, use the following dm commands in the shell:
dm shutdown
dm reboot
See Connect to a target shell for more information.
Select a tab
Fuchsia shows multiple tabs in the shell. At the top of the screen, the currently selected tab is highlighted in yellow.
The following keyboard shortcuts help you navigate the terminal:
- Alt+Tab switches between tabs.
- Alt+F{1,2,...} switches directly to a tab.
- Tab zero is the console, which displays the boot and component log.
- Tabs 1, 2 and 3 contain shells.
- Tabs 4 and higher contain components you've launched.
- Alt+Up/Down scrolls up and down by lines.
- Shift+PgUp/PgDown scrolls up and down by half page.
- Ctrl+Alt+Delete reboots.

Run tests
To test Fuchsia on your device, see Run Fuchsia tests.
Launch a graphical component
Most graphical components in Fuchsia use the
Scenic system compositor. You can
launch such components (commonly found in /system/apps) using the
present_view command, for example:
present_view fuchsia-pkg://fuchsia.com/spinning_square_view#meta/spinning_square_view.cmx
See Scenic example apps.
If you launch a component that uses Scenic or hardware-accelerated graphics,
Fuchsia enters the graphics mode, which doesn't display the shell. To use the
shell, press Alt+Escape to enter the console mode. In the console mode,
Alt+Tab has the same behavior described in Select a tab.
Press Alt+Escape again to return to the graphics mode.
