adb shell cmd input

Usage: input [<source>] [-d DISPLAY_ID] <command> [<arg>...]

The sources are: 
      touchnavigation
      touchscreen
      joystick
      stylus
      touchpad
      gamepad
      dpad
      mouse
      keyboard
      trackball
      rotaryencoder
[axis_value] represents an option specifying the value of a given axis 
      The syntax is as follows: --axis <axis_name>,<axis_value>
            where <axis_name> is the name of the axis as defined in 
            MotionEvent without the AXIS_ prefix (e.g. SCROLL, X)
      Sample [axis_values] entry: `--axis Y,3`, `--axis SCROLL,-2`

-d: specify the display ID.
      (Default: -1 for key event, 0 for motion event if not specified.)
The commands and default sources are:
      text <string> (Default: keyboard)
      keyevent [--longpress|--duration <duration to hold key down in ms>] [--doubletap] [--async] [--delay <duration between keycodes in ms>] <key code number or name> ... (Default: keyboard)
      tap <x> <y> (Default: touchscreen)
      swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)
      draganddrop <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)
      press (Default: trackball)
      roll <dx> <dy> (Default: trackball)
      motionevent <DOWN|UP|MOVE|CANCEL> <x> <y> (Default: touchscreen)
      scroll (Default: rotaryencoder). Has the following syntax:
            scroll <x> <y> [axis_value] (for pointer-based sources)
            scroll [axis_value] (for non-pointer-based sources)
            Axis options: SCROLL, HSCROLL, VSCROLL
            None or one or multiple axis value options can be specified.
            To specify multiple axes, use one axis option for per axis.
            Example: `scroll --axis VSCROLL,2 --axis SCROLL,-2.4`
      keycombination [-t duration(ms)] <key code 1> <key code 2> ... (Default: keyboard, the key order is important here.)

adb shell cmd user
Output: 
User manager (user) commands:
  help
    Prints this help text.

  list [-v | --verbose] [-V | --very-verbose] [--all]
    Prints all users on the system.

  report-system-user-package-whitelist-problems [-v | --verbose] [--critical-only] [--mode MODE]
    Reports all issues on user-type package allowlist XML files. Options:
    -v | --verbose: shows extra info, like number of issues
    --critical-only: show only critical issues, excluding warnings
    --mode MODE: shows what errors would be if device used mode MODE
      (where MODE is the allowlist mode integer as defined by config_userTypePackageWhitelistMode)

  set-system-user-mode-emulation [--reboot | --no-restart] <headless | full | default>
    Changes whether the system user is headless, full, or default (as defined by OEM).
    WARNING: this command is meant just for development and debugging purposes.
             It should NEVER be used on automated tests.
    NOTE: by default it restarts the Android runtime, unless called with
          --reboot (which does a full reboot) or
          --no-restart (which requires a manual restart)

  is-headless-system-user-mode [-v | --verbose]
    Checks whether the device uses headless system user mode.
  is-visible-background-users-on-default-display-supported [-v | --verbose]
    Checks whether the device allows users to be start visible on background in the default display.
    It returns the effective mode, even when using emulation
    (to get the real mode as well, use -v or --verbose)

  is-visible-background-users-supported [-v | --verbose]
    Checks whether the device allows users to be start visible on background.
    It returns the effective mode, even when using emulation
    (to get the real mode as well, use -v or --verbose)

  is-user-visible [--display DISPLAY_ID] <USER_ID>
    Checks if the given user is visible in the given display.
    If the display option is not set, it uses the user's context to check
    (so it emulates what apps would get from UserManager.isUserVisible())

  get-main-user 
    Displays main user id or message if there is no main user

  grant-admin <USER_ID>
    Grants admin privileges to the given user (requires adb root)

  revoke-admin <USER_ID>
    Revokes admin privileges from the given user (requires adb root)
