How Do I Use Command Line Flags in Brave? Takip et
Opening Brave Using Command Prompt
To open Brave With Command Prompt:
- Quit Brave
- Open Command Prompt
- Enter:
"C:\Program Files (x86)\BraveSoftware\Brave-Browser\Application\brave.exe"
This will open Brave just as it would if you clicked on the icon. It is the path to your Brave application inside double quotes. For users on Beta or Nightly builds the path will be the same, but will have the build name appended:
C:\Program Files (x86)\BraveSoftware\Brave-Browser-Beta\Application\brave.exeC:\Program Files (x86)\BraveSoftware\Brave-Browser-Nightly\Application\brave.exe
But for reference you can easily obtain the path by navigating to Brave’s shortcut either on the Desktop or in the Start Menu, going to its Properties and then copying Target.
Opening Brave With A Flag
To launch Brave with a flag, instead, enter a command like this:
"C:\Program Files (x86)\BraveSoftware\Brave-Browser\Application\brave.exe" --incognito
--incognito is a command line flag (sometimes called a “switch”), and by adding it to the end of the path we can open Brave in a Private Window. Note that you must add the flag after the quotations, to avoid “invalid path” errors.
You can also enable flags by adding them to the end of the Target path, mentioned above. To do this:
- Quit Brave
- Right click on the Brave shortcut
- Go to
Properties - And within the
Targetbox add--incognitoto the end (after the ending quotation) - Apply the changes
- Launch Brave using the shortcut icon
For a full list of command line flags, see below.
Opening Brave Using Terminal
To open Brave With Terminal
- Quit Brave
- Open Terminal
- Enter the command:
open -a "Brave Browser.app"
The open command opens a file just as if you had double clicked the file's icon. -a tells open what application to use. For users on Beta or Nightly builds the path will be the same, but will have the build name appended:
open -a "Brave Browser Beta.app"open -a "Brave Browser Nightly.app"
Opening Brave With A Flag
To launch Brave with a flag, instead, enter a command like this:
open -a "Brave Browser.app" -n --args --incognito
This command will open Brave but in a Private Window. -n tells open to open a new instance of the application (note that the -n is not necessary if you properly quit any running instance of Brave, but it is recommended). --args allows for the following arguments (flags) to be passed to the application when launched, rather than the arguments being interpreted by open.
This is only needed if you’re adding a flag. --incognito is a command line flag (also known as switch), all flags have to follow after --args.
For a full list of command line flags, see below.
List of Command Line Flags/Switches
Below is a list of all available flags, please note that some flags may be outdated or geared towards Chromium and may not work for Brave.
| Condition | Explanation |
|---|---|
| -/prefetch:1 | /prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. |
| --/prefetch:2 | No description |
| --/prefetch:3 | No description |
| --/prefetch:4 | No description |
| --/prefetch:5 | /prefetch:# arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on kPrefetchArgument* in content_switches.cc. |
| --/prefetch:6 | No description |
| --/prefetch:8 | Prefetch arguments are used by the Windows prefetcher to disambiguate different execution modes (i.e. process types) of the same executable image so that different types of processes don't trample each others' prefetch behavior. Legal values are integers in the range [1, 8]. We reserve 8 to mean "whatever", and this will ultimately lead to processes with /prefetch:8 having inconsistent behavior thus disabling prefetch in practice. TODO(rockot): Make it possible for embedders to override this argument on a per-service basis. |

| --accept-resource-provider | Flag indicating that a resource provider must be set up to provide cast receiver with resources. Apps cannot start until provided resources. This flag implies --alsa-check-close-timeout=0. |
| --account-consistency | Command line flag for enabling account consistency. Default mode is disabled. Mirror is a legacy mode in which Google accounts are always addded to Chrome, and Chrome then adds them to the Google authentication cookies. Dice is a new experiment in which Chrome is aware of the accounts in the Google authentication cookies. |

Any other value will lead to Chrome detecting the best backend automatically. TODO(crbug.com/571003): Once PasswordStore no longer uses the Keyring or KWallet for storing passwords, rename this flag to stop referencing passwords. Do not rename it sooner, though; developers and testers might rely on it keeping large amounts of testing passwords out of their Keyrings or KWallets. |

| --process-per-site | Enable the "Process Per Site" process model for all domains. This mode consolidates same-site pages so that they share a single process. More details here: - https://www.chromium.org/developers/design-documents/process-models - The class comment in site_instance.h, listing the supported process models. IMPORTANT: This isn't to be confused with --site-per-process (which is about isolation, not consolidation). You probably want the other one. |
| --process-per-tab | Runs each set of script-connected tabs (i.e., a BrowsingInstance) in its own renderer process. We default to using a renderer process for each site instance (i.e., group of pages from the same registered domain with script connections to each other). TODO(creis): This flag is currently a no-op. We should refactor it to avoid "unnecessary" process swaps for cross-site navigations but still swap when needed for security (e.g., isolated origins). |

This will only work if chrome has been built with the gyp variable profiling=1 or gn arg enable_profiling=true. {pid} if present will be replaced by the pid of the process. {count} if present will be incremented each time a profile is generated for this process. The default is chrome-profile-{pid} for the browser and test-profile-{pid} for tests. |
| --profiling-flush | Controls whether profile data is periodically flushed to a file. Normally the data gets written on exit but cases exist where chromium doesn't exit cleanly (especially when using single-process). A time in seconds can be specified. |

| --run-web-tests | Request the render trees of pages to be dumped as text once they have finished loading. |
| --run-without-sandbox-for-testing | Load the engine outside the sandbox. This is only to be used for manual testing. |
| --safebrowsing-manual-download-blacklist | List of comma-separated sha256 hashes of executable files which the download-protection service should treat as "dangerous." For a file to show a warning, it also must be considered a dangerous filetype and not be whitelisted otherwise (by signature or URL) and must be on a supported OS. Hashes are in hex. This is used for manual testing when looking for ways to by-pass download protection. |
| --SafeSites | No description |

| --single-process | Runs the renderer and plugins in the same process as the browser |
| --site-per-process | Enforces a one-site-per-process security policy: * Each renderer process, for its whole lifetime, is dedicated to rendering pages for just one site. * Thus, pages from different sites are never in the same process. * A renderer process's access rights are restricted based on its site. * All cross-site navigations force process swaps. * <iframe>s are rendered out-of-process whenever the src= is cross-site. More details here: - https://www.chromium.org/developers/design-documents/site-isolation - https://www.chromium.org/developers/design-documents/process-models - The class comment in site_instance.h, listing the supported process models. IMPORTANT: this isn't to be confused with --process-per-site (which is about process consolidation, not isolation). You probably want this one. |

| --sync-deferred-startup-timeout-seconds | Allows overriding the deferred init fallback timeout. |
| --sync-disable-deferred-startup | Enables deferring sync backend initialization until user initiated changes occur. |
| --sync-enable-get-update-before-commits | TODO(crbug.com/657130): Sync integration tests depend on the precommit get updates because invalidations aren't working for them. Therefore, they pass the command line switch to enable this feature. Once sync integrations test support invalidation, this should be removed. Enables feature to perform GetUpdate requests before every commit. |

| --tether-host-scans-ignore-wired-connections | Tells the Chromebook to scan for a tethering host even if there is already a wired connection. This allows end-to-end tests to be deployed over ethernet without that connection preventing scans and thereby blocking the testing of cases with no preexisting connection. Should be used only for testing. |
| --tether-stub | Overrides Tether with stub service. Provide integer arguments for the number of fake networks desired, e.g. 'tether-stub=2'. |
| --third-party-doodle-url | Overrides the Doodle URL to use for third-party search engines. Testing? Try: https://www.gstatic.com/chrome/ntp/doodle_test/third_party_simple.json https://www.gstatic.com/chrome/ntp/doodle_test/third_party_animated.json |
| --timeout | Issues a stop after the specified number of milliseconds. This cancels all navigation and causes the DOMContentLoaded event to fire. |

| --touch_view | No description |
| --trace-config-file | Causes TRACE_EVENT flags to be recorded from startup. This flag will be ignored if --trace-startup or --trace-shutdown is provided. |
| --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-startup-owner | Specifies the coordinator of the startup tracing session. If the legacy tracing backend is used instead of perfetto, providing this flag is not necessary. Valid values: 'controller', 'devtools', or 'system'. Defaults to 'controller'. If 'controller' is specified, the session is controlled and stopped via the TracingController (e.g. to implement the timeout). If 'devtools' is specified, the startup tracing session will be owned by DevTools and thus can be controlled (i.e. stopped) via the DevTools Tracing domain on the first session connected to the browser endpoint. If 'system' is specified, the system Perfetto service should already be tracing on a supported platform (currently only Android). Session is stopped through the normal methods for stopping system traces. |
| --trace-startup-record-mode | If supplied, sets the tracing record mode; otherwise, the default "record-until-full" mode will be used. |
| --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. |
| --trace-upload-url | Sets the target URL for uploading tracing data. |
| --translate-ranker-model-url | Overrides the URL from which the translate ranker model is downloaded. |
| --translate-script-url | Overrides the default server used for Google Translate. |

| --true | Value indicating whether flag from command line switch is true. |
| --trustable-bundled-exchanges-file | Accepts specified file as a trustable BundledExchanges file. This flag should be used only for testing purpose. |
| --trusted-cdn-base-url-for-tests | Specifies a base URL for the trusted CDN for tests. |
| --trusted-download-sources | Identifies a list of download sources as trusted, but only if proper group policy is set. |
| --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 | 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. |
| --type | Indicates the type of process to run. This may be "service-manager", "service-runner", or any other arbitrary value supported by the embedder. |

| --uninstall | Runs un-installation steps that were done by chrome first-run. |
| --unlimited-storage | Overrides per-origin quota settings to unlimited storage for any apps/origins. This should be used only for testing purpose. |
| --unsafely-allow-protected-media-identifier-for-domain | For automated testing of protected content, this switch allows specific domains (e.g. example.com) to skip asking the user for permission to share the protected media identifier. In this context, domain does not include the port number. User's content settings will not be affected by enabling this switch. Reference: http://crbug.com/718608 Example: --unsafely-allow-protected-media-identifier-for-domain=a.com,b.ca |
| --unsafely-treat-insecure-origin-as-secure | Treat given (insecure) origins as secure origins. Multiple origins can be supplied as a comma-separated list. For the definition of secure contexts, see https://w3c.github.io/webappsec-secure-contexts/ and https://www.w3.org/TR/powerful-features/#is-origin-trustworthy Example: --unsafely-treat-insecure-origin-as-secure=http://a.test,http://b.test |
| --upgrade-token | No description |
| --upload-log-file | Specifies the full path to a protocol buffer log file to be uploaded. |
| --use-angle | Select which ANGLE backend to use. Options are: default: Attempts several ANGLE renderers until one successfully initializes, varying ES support by platform. d3d9: Legacy D3D9 renderer, ES2 only. d3d11: D3D11 renderer, ES2 and ES3. warp: D3D11 renderer using software rasterization, ES2 and ES3. gl: Desktop GL renderer, ES2 and ES3. gles: GLES renderer, ES2 and ES3. |
| --use-cmd-decoder | Use the Pass-through command decoder, skipping all validation and state tracking. Switch lives in ui/gl because it affects the GL binding initialization on platforms that would otherwise not default to using EGL bindings. |
| --use-cras | Use CRAS, the ChromeOS audio server. |
| --use-crash-handler-in-tests | If present, the test harness will use the crash reporter. |
| --use-crash-handler-with-id | Specifies the IPC pipe name of the crash handler to use (instead of starting a new crash handler process). |
| --use-fake-codec-for-peer-connection | Replaces the existing codecs supported in peer connection with a single fake codec entry that create a fake video encoder and decoder. |
| --use-fake-device-for-media-stream | Use fake device for Media Stream to replace actual camera and microphone. |
| --use-fake-mjpeg-decode-accelerator | Use a fake device for accelerated decoding of MJPEG. This allows, for example, testing of the communication to the GPU service without requiring actual accelerator hardware to be present. |
| --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. You can pass either <path> to play the file looping or <path>%noloop to stop after playing the file to completion. |
| --use-file-for-fake-video-capture | Use an .y4m file to play as the webcam. See the comments in media/capture/video/file_video_capture_device.h for more details. |

| --user-agent | A string used to override the default user agent with a custom one. |
| --user-always-affiliated | Always treat user as affiliated. TODO(antrim): Remove once test servers correctly produce affiliation ids. |
| --user-data-dir | Directory where the browser stores the user profile. |
| --user-gesture-required | Autoplay policy to require a user gesture in order to play. |
| --user-response-timeout | Set the timeout for how long to wait for user response from Chrome, in minutes. 0 disables the timeout entirely. |
| --utility | No description |
| --utility-and-browser | No description |
| --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-sampling | No description |
| --utility-startup-dialog | Causes the utility process to display a dialog on launch. |
| --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) |
| --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. |
| --validating | The command decoder names that can be passed to --use-cmd-decoder. |
| --variations-insecure-server-url | Specifies a custom URL for the server to use as an insecure fallback when requests to |kVariationsServerURL| fail. Requests to this URL will be encrypted. |
| --variations-override-country | Allows overriding the country used for evaluating variations. This is similar to the "Override Variations Country" entry on chrome://translate-internals, but is exposed as a command-line flag to allow testing First Run scenarios. Additionally, unlike chrome://translate-internals, the value isn't persisted across sessions. |
| --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 | No description |
| --video-image-texture-target | Texture target for CHROMIUM_image backed video frame textures. |
| --video-threads | Set number of threads to use for video decoding. |
| --video-underflow-threshold-ms | Allows clients to override the threshold for when the media renderer will declare the underflow state for the video stream when audio is present. TODO(dalecurtis): Remove once experiments for http://crbug.com/470940 finish. |
| --virtual-time-budget | If set the system waits the specified number of virtual milliseconds before deeming the page to be ready. For determinism virtual time does not advance while there are pending network fetches (i.e no timers will fire). Once all network fetches have completed, timers fire and if the system runs out of virtual time is fastforwarded so the next timer fires immediatley, until the specified virtual time budget is exhausted. |
| --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. |
| --vsync-interval | Overrides the vsync interval used by the GPU process to refresh the display. |
| --vulkan | No description |
| --vulkan-null | No description |
| --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-initial-policy-fetch-for-test | Used to tell the policy infrastructure to not let profile initialization complete until policy is manually set by a test. This is used to provide backward compatibility with a few tests that incorrectly use the synchronously-initialized login profile to run their tests - do not add new uses of this flag. |
| --wake-on-wifi-packet | Enables wake on wifi packet feature, which wakes the device on the receipt of network packets from whitelisted sources. |

| --webrtc-event-log-proactive-pruning-delta | Sets the delay (in seconds) between proactive prunings of remote-bound WebRTC event logs which are pending upload. All positive values are legal. All negative values are illegal, and ignored. If set to 0, the meaning is "no proactive pruning". |
| --webrtc-event-log-upload-delay-ms | WebRTC event logs will only be uploaded if the conditions hold for this many milliseconds. |
| --webrtc-event-log-upload-no-suppression | Normally, remote-bound WebRTC event logs are uploaded only when no peer connections are active. With this flag, the upload is never suppressed. |
| --webrtc-event-logging | Enable capture and local storage of WebRTC event logs without visiting chrome://webrtc-internals. This is useful for automated testing. It accepts the path to which the local logs would be stored. Disabling is not possible without restarting the browser and relaunching without this flag. |
| --webrtc-max-cpu-consumption-percentage | Configure the maximum CPU time percentage of a single core that can be consumed for desktop capturing. Default is 50. Set 100 to disable the throttling of the capture. |
| --webrtc-stun-probe-trial | Renderer process parameter for WebRTC Stun probe trial to determine the interval. Please see SetupStunProbeTrial in chrome_browser_field_trials_desktop.cc for more detail. |
