Chrome Command Line



  • When you open Chrome from the command-line, it opens the default or last opened Chrome profile. As of now, there is no way to open a specific Chrome profile. If you want to open a specific Chrome profile, I recommend you make that profile the default one in Windows. Also, as of now, there is no way to open multiple URLs from the command line.
  • Chrome browser supports opening from command line and run window. There are few command line switches as well that you can use to launch chrome incognito mode or with other features. Open chrome from command line. Run below command to start chrome from CMD.
  • Launch Google Chrome from the command line with specific window coordinates. Host-rules google chrome, adding configuration. How to force Chrome browser to reload.css file while debugging in Visual Studio? Chrome.exe command line parameters for kiosk mode.
  • FWIW, here is the Mac version, you can put this in your.bashprofile file: # Launch Chrome with given URL from command line alias url='open -a 'Google Chrome.app'.

Open chrome settings from command line

There are command line flags (or 'switches') that Chromium (and Chrome) accept in order to enable particular features or modify otherwise default functionality.

Current switches may be found at http://peter.sh/examples/?/chromium-switches.html

It is important to note that some switches are intended for temporary cases and may break in the future.

AddListener (function (command) console. Log ( 'Command:', command ); The 'executebrowseraction' and 'executepageaction' commands are reserved for the action of opening your extension's popups.

Chrome Command Line Linux

Note that if you look at chrome://flags to see if the command line option is active, the state might not be accurately reflected. Check chrome://version for the complete command line used in the current instance.

Chrome command line args

Windows

  1. Exit any running-instance of Chrome.
  2. Right click on your 'Chrome' shortcut.
  3. Choose properties.
  4. At the end of your 'Target:' line add the command line flags. For example:
    • --disable-gpu-vsync
  5. With that example flag, it should look like below (replacing '--disable-gpu-vsync' with any other command line flags you want to use):
    chrome.exe --disable-gpu-vsync
  6. Launch Chrome like normal with the shortcut.

macOS

  1. Quit any running instance of Chrome.
  2. Run your favorite Terminal application.
  3. In the terminal, run commands like below (replacing '--remote-debugging-port=9222' with any other command line flags you want to use):
    /Applications/Chromium.app/Contents/MacOS/Chromium --remote-debugging-port=9222
    # For Google Chrome you'll need to escape spaces like so:
    /Applications/Google Chrome.app/Contents/MacOS/Google Chrome --remote-debugging-port=9222

Linux

  1. Quit any running instance of Chrome.
  2. Run your favorite terminal emulator.
  3. In the terminal, run commands like below (replacing '--remote-debugging-port=9222' with any other command line flags you want to use):
    chromium-browser --remote-debugging-port=9222
    google-chrome --foo --bar=2

V8 Flags

V8 can take a number of flags as well, via Chrome's js-flags flag. For example, this traces V8 optimizations:

chrome.exe --js-flags='--trace-opt --trace-deopt --trace-bailout'

To get a listing of all possible V8 flags:

Browse the V8 wiki for more flags for V8.

Android

Visit 'about:version' to review the flags that are effective in the app.

If you are running on a rooted device or using a debug build of Chromium, then you can set flags like so:

out/Default/bin/chrome_public_apk argv # Show existing flags.
out/Default/bin/content_shell_apk argv --args='--foo --bar' # Set new flags

You can also install, set flags, and launch with a single command:

out/Default/bin/chrome_public_apk run --args='--foo --bar'
out/Default/bin/content_shell_apk run # Clears any existing flags

For production build on a non-rooted device, you need to enable 'Enable command line on non-rooted devices' in chrome://flags, then set command line in /data/local/tmp/chrome-command-line. When doing that, mind that the first command line item should be a '_' (underscore) followed by the ones you actually need. Finally, manually restart Chrome ('Relaunch' from chrome://flags page might no be enough to trigger reading this file). See https://crbug.com/784947.

ContentShell on Android

There's an alternative method for setting flags with ContentShell that doesn't require building yourself:

  1. Download a LKGR build of Android.
  2. This will include both ChromePublic.apk and ContentShell.apk
  3. Install ContentShell APK to your device.
  4. Run this magic incantation
-a android.intent.action.VIEW
-n org.chromium.content_shell_apk/.ContentShellActivity
--esa commandLineArgs --show-paint-rects,--show-property-changed-rects

This will launch contentshell with the supplied flags. You can apply whatever commandLineArgs you want in that syntax.
