This code exports the DISPLAY environment variable to redirect the display to the first display, then launches Google Chrome in full-screen mode to open a development server at http://localhost:4200. It appears to be a Linux-specific script used for testing or demonstration purposes.

Cell 2

export DISPLAY=:0
google-chrome http://localhost:4200 --no-sandbox --start-fullscreen

#!/bin/bash

# Set the display to the default display
export DISPLAY=:0

# Start Google Chrome with the given URL in fullscreen mode
start_browser() {
  local url=$1
  local flags="--no-sandbox --start-fullscreen"

  # Start Chrome with the given URL and flags
  google-chrome "$url" $flags
}

# Call the function to start the browser
start_browser http://localhost:4200

Code Breakdown

Export Environment Variable

• export DISPLAY=:0: Exports the DISPLAY environment variable and sets its value to :0.
  • This variable specifies the display identifier for the X Window System.
  • In this case, it's set to :0, which means the display is being redirected to the first display (index 0).

Run Google Chrome

• google-chrome: Launches the Google Chrome browser.
• http://localhost:4200: Specifies the URL to open in the browser.
• --no-sandbox: Disables the sandboxing feature, which can be useful for debugging or running Chrome in a server environment.
• --start-fullscreen: Starts the browser in full-screen mode.

Context

• This code is likely being run on a Linux system, given the use of the export command and the presence of the DISPLAY variable.
• It's being used to launch a development server (http://localhost:4200) in a browser, possibly for testing or demonstration purposes.
