There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2015-03-22.

Condition Explanation
--0  Value of the --profiler-timing flag that will disable timing information for chrome://profiler. 
--aggressive  No description 
--aggressive-cache-discard  No description 
--aggressive-tab-discard  No description 
--allow-autofill-sync-credential  Force the password manager to allow sync credentials to be autofilled. 
--allow-cross-origin-auth-prompt  Allows third-party content included on a page to prompt for a HTTP basic auth username/password pair. 
--allow-external-pages  Allow access to external pages during layout tests. 
--allow-file-access  On ChromeOS, file:// access is disabled except for certain whitelisted directories. This switch re-enables file:// for testing. 
--allow-file-access-from-files  By default, file:// URIs cannot read other file:// URIs. This is an override for developers who need the old behavior for testing. 
--allow-http-background-page  Allows non-https URL for background_page for hosted apps. 
--allow-http-screen-capture  Allow non-secure origins to use the screen capture API and the desktopCapture extension API. 
--allow-insecure-localhost  Enables TLS/SSL errors on localhost to be ignored (no interstitial, no blocking of requests). 
--allow-insecure-websocket-from-https-origin  Allows frames with an https origin to use WebSockets with an insecure URL (ws://). 
--allow-legacy-extension-manifests  Allows the browser to load extensions that lack a modern manifest when that would otherwise be forbidden.

--allow-no-sandbox-job  Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in RemoteApps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard. Also we lose the chance to kill some processes until the outer job that owns them finishes. 
--allow-outdated-plugins  Don't block outdated plugins. 
--allow-running-insecure-content  By default, an https page cannot run JavaScript, CSS or plugins from http URLs. This provides an override to get the old insecure behavior.

(Note that a page can reference content from multiple origins due to images, JavaScript files, etc. Cross-site iframes are also loaded in-process.) 2) Only has authority to see or use cookies for the page's top-level origin. (So if a.com iframes b.com, the b.com network request will be sent without cookies.) This is expected to break compatibility with many pages for now. Unlike the --site-per-process flag, this allows cross-site iframes, but it blocks all cookies on cross-site requests.

For details, see: http://www.chromium.org/developers/design-documents/site-isolation Unlike --enable-strict-site-isolation (which allows cross-site iframes), this flag does not affect which cookies are attached to cross-site requests. Support is being added to render cross-site iframes in a different process than their parent pages. 
--skip-gpu-data-loading  Skip gpu info collection, blacklist loading, and blacklist auto-update scheduling at browser startup time. Therefore, all GPU features are available, and about:gpu page shows empty content. The switch is intended only for layout tests. TODO(gab): Get rid of this switch entirely.

--stable-release-mode  This makes us disable some web-platform runtime features so that we test content_shell as if it was a stable release. It is only followed when kRunLayoutTest is set. For the features' level, see http://dev.chromium.org/blink/runtime-enabled-features. 
--start  No description

--trace-shutdown  Causes TRACE_EVENT flags to be recorded beginning with shutdown. Optionally, can specify the specific trace categories to include (e.g. --trace-shutdown=base,net) otherwise, all events are recorded. --trace-shutdown-file can be used to control where the trace log gets stored to since there is otherwise no way to access the result. 
--trace-shutdown-file  If supplied, sets the file which shutdown tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-shutdown is also supplied. Example: --trace-shutdown --trace-shutdown-file=/tmp/trace_event.log 
--trace-startup  Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component). 
--trace-startup-duration  Sets the time in seconds until startup tracing ends. If omitted a default of 5 seconds is used. Has no effect without --trace-startup, or if --startup-trace-file=none was supplied. 
--trace-startup-file  If supplied, sets the file which startup tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-startup is also supplied. Example: --trace-startup --trace-startup-file=/tmp/trace_event.log As a special case, can be set to 'none' - this disables automatically saving the result to a file and the first manually recorded trace will then receive all events since startup.
--trace-to-console  Sends a pretty-printed version of tracing info to the console. 
--trace-to-file  Sends trace events from these categories to a file. --trace-to-file on its own sends to default categories. 
--trace-to-file-name  Specifies the file name for --trace-to-file. If unspecified, it will go to a default file name.

--try-chrome-again  Experimental. Shows a dialog asking the user to try chrome. This flag is to be used only by the upgrade process. 
--try-supported-channel-layouts[4]  Instead of always using the hardware channel layout, check if a driver supports the source channel layout. Avoids outputting empty channels and permits drivers to enable stereo to multichannel expansion. Kept behind a flag since some drivers lie about supported layouts and hang when used. See http://crbug.com/259165 for more details. 
--ttl  No description 
--type  The value of this switch determines whether the process is started as a renderer or plugin host. If it's empty, it's the browser.

--use-fake-ui-for-media-stream  Bypass the media stream infobar by selecting the default device for media streams (e.g. WebRTC). Works with --use-fake-device-for-media-stream. 
--use-file-for-fake-audio-capture  Play a .wav file as the microphone. Note that for WebRTC calls we'll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). The input file is converted to suit Chrome's audio buses if necessary, so most sane .wav files should work. 
--use-file-for-fake-video-capture  Use an .y4m file to play as the webcam. See the comments in media/video/capture/file_video_capture_device.h for more details. 
--use-gl  Select which implementation of GL the GPU process should use. Options are: desktop: whatever desktop OpenGL the user has installed (Linux and Mac default). egl: whatever EGL / GLES2 the user has installed (Windows default - actually ANGLE). osmesa: The OSMesa software renderer.

TODO(hidehiko): Make this default and then remove this flag after nacl_helper_nonsfi is supported. 
--use-normal-priority-for-tile-task-worker-threads  Use normal priority for tile task worker threads. Otherwise they may be run at background priority on some platforms. 
--use-simple-cache-backend  Uses experimental simple cache backend if possible. 
--use-spdy  Uses Spdy for the transport protocol instead of HTTP. This is a temporary testing flag.

--video-threads  Set number of threads to use for video decoding. 
--viewer-launch-via-appid[4]  Requests that Chrome launch the Metro viewer process via the given appid (which is assumed to be registered as default browser) and synchronously connect to it. 
--vmodule  Gives the per-module maximal V-logging levels to override the value given by --v. E.g. "my_module=2,foo*=3" would change the logging level for all code in source files "my_module.*" and "foo*.*" ("-inl" suffixes are also disregarded for this matching). Any pattern containing a forward or backward slash will be tested against the whole pathname and not just the module. E.g., "*/foo/bar/*=2" would change the logging level for all code in source files under a "foo/bar" directory. 
--wait-for-debugger  Will wait for 60 seconds for a debugger to come to attach to the process. 
--wait-for-debugger-children  Will add kWaitForDebugger to every child processes. If a value is passed, it will be used as a filter to determine if the child process should have the kWaitForDebugger flag passed on or not.
