1. Screenshot

Description (no more than one connected device):

1. Sets device in demo mode: hides your notifications, fixed clock, full battery, wifi level)
2. Takes a screenshot and saves it into captures directory. Also to your clipboard, so it's ready for Paste
3. Exits demo mode

Usage:

1. Download screenshot.sh
2. chmod +x screenshot.sh
3. Optional, MacOS: Automator → New Quck Action → Run Shell Script Insert:

   
     export PATH="your env PATH"
     cd ~/dev/scripts
     ./screenshot.sh
    

   Add it to your TouchBar (add Quick Actions group) or assign a global hot key Keyboard → Shortcuts → Service → Screenshot

2. GIF/MP4 recorder

Dependencies: brew install ffmpeg

Description:

1. Sets device in demo mode
2. Starts recording and awaits for Ctrl + C
3. MP4 clip is downloaded and removed from device, gif encoded and saved to captures
4. Exits demo mode

Usage:

1. Download recorder.sh
2. chmod +x recorder.sh
3. Optional, MacOS, iTerm: Automator → New Quck Action → AppleScript Insert:

  on run {input, parameters}
	
	tell application "iTerm"
		activate
		tell current window
			create tab with default profile
		end tell
		
		tell first session of current tab of current window
			write text "cd ~/dev/scripts&&./recorder.sh"
			--write text "./recorder.sh"
		end tell
		
	end tell

Add it to your TouchBar (add Quick Actions group) or assign a global hot key Keyboard → Shortcuts → Service → Recorder
