chrome 谷歌浏览器命令行大全

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.

ConditionExplanation
--0 ⊗Value of the --profiler-timing flag that will disable timing information for chrome://profiler. ↪

--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. ↪

(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. ↪

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.↪

--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. ↪

--use-nacl-helper-nonsfi ⊗Use nacl_helper_nonsfi executable (the new, newlib-based version of the Non-SFI runtime) to run Non-SFI nexe, instead of nacl_helper executable (which uses the older, glib-based runtime for Non-SFI mode). 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. ↪
--use-surfaces ⊗Use the new surfaces system to handle compositor delegation. ↪
--use-warp ⊗On Windows only: use the WARP software rasterizer in the GPU process. ↪
--user-agent ⊗A string used to override the default user agent with a custom one. ↪
--user-data-dir ⊗Specifies the user data directory, which is where the browser will look for all of its state. ↪
--utility ⊗Causes the process to run as a utility subprocess. ↪
--utility-allowed-dir ⊗The utility process is sandboxed, with access to one directory. This flag specifies the directory that can be accessed. ↪
--utility-cmd-prefix ⊗The contents of this flag are prepended to the utility process command line. Useful values might be "valgrind" or "xterm -e gdb --args". ↪
--utility-enable-mdns ⊗Allows MDns to access network in sandboxed process. ↪
--utility-run-elevated ⊗No description ↪
--v ⊗Gives the default maximal active V-logging level; 0 is the default. Normally positive values are used for V-logging levels. ↪
--v8-cache-options ⊗Set options to cache V8 data. (off, preparse data, or code) ↪
--v8-pac-mojo-in-process ⊗Enables using an in-process Mojo service for the v8 proxy resolver. ↪
--v8-pac-mojo-out-of-process ⊗Enables using an out-of-process Mojo service for the v8 proxy resolver. ↪
--validate-crx ⊗Examines a .crx for validity and prints the result. ↪
--validate-input-event-stream ⊗In debug builds, asserts that the stream of input events is valid. ↪
--variations-server-url ⊗Specifies a custom URL for the server which reports variation data to the client. Specifying this switch enables the Variations service on unofficial builds. See variations_service.cc. ↪
--version ⊗Prints version information and quits. ↪
--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. ↪
--wait-for-mutex[4] ⊗Waits for the given handle to be signaled before relaunching metro Chrome on Windows 8 and higher.↪
--wake-on-packets ⊗Enables waking the device based on the receipt of some network packets. ↪
--wallet-secure-service-url ⊗Secure service URL for Online Wallet service. Used as the base url to escrow credit card numbers. ↪
--wallet-service-url ⊗Service URL for Online Wallet service. Used as the base url for Online Wallet API calls. ↪
--wallet-service-use-sandbox ⊗Use the sandbox Online Wallet service URL (for developer testing). ↪
--waveout-buffers[4] ⊗Number of buffers to use for WaveOut. ↪
--whitelisted-extension-id ⊗Adds the given extension ID to all the permission whitelists. ↪
--win-jumplist-action ⊗Specifies which category option was clicked in the Windows Jumplist that resulted in a browser startup.↪
--window-position ⊗Specify the initial window position: --window-position=x,y ↪
--window-size ⊗Specify the initial window size: --window-size=w,h ↪
--winhttp-proxy-resolver ⊗Uses WinHTTP to fetch and evaluate PAC scripts. Otherwise the default is to use Chromium's network stack to fetch, and V8 to evaluate. ↪
--wm-window-animations-disabled ⊗If present animations are disabled. ↪
--zygote ⊗Causes the process to run as a renderer zygote. ↪
