How to specify command line flags

Let's say that you want to add two command line flags to chrome: --foo and --bar=2.


  1. Exit any running-instance of chrome.
  2. Find the shortcut you normally use to launch chrome.
  3. Create a copy of it
  4. Right click on the new shortcut, and select Properties
  5. At the very end of the Target: text box, add a space and then the desired command line flags. 
    It should end in something like ...\chrome.exe" --foo --bar=2
  6. Double click the new shortcut to launch chrome with the new command line flags.

Mac OS X

  1. Quit any running instance of chrome.
  2. Launch /Applications/Utilities/
  3. At the command prompt enter:
    /Applications/Google\\ Chrome --foo --bar=2


  1. Exit any running instance of chrome.
  2. Execute in a console:
    google-chrome --foo --bar=2

    (If you are using a different named chrome/chromium build, change the command accordingly)

Chrome OS

  1. Put the device into dev mode so you can get a root shell
  2. Modify /etc/chrome_dev.conf (read the comments in the file for more details)
  3. Restart the UI via:
    sudo restart ui
