chromium-browser(1)

NAME
chromium-browser - the web browser from Google

SYNOPSIS
chromium-browser [OPTION] [PATH|URL]

DESCRIPTION
See the Google Chrome help center for help on using the browser.

    <https://support.google.com/chrome/>

This manpage only describes invocation, environment, and arguments.

OPTIONS
Chromium has hundreds of undocumented command-line flags that are added and removed at the whim of the developers. Here, we document relatively stable flags.

--user-data-dir=DIR
    Specifies the directory that user data (your "profile") is kept in. Defaults to ~/.config/chromium . Separate instances of Chromium must use separate user data directories; repeated invocations of chromium-browser will reuse an existing process for a given user data directory.

--app=URL
    Runs URL in "app mode": with no browser toolbars.

--incognito
    Open in incognito mode.

--proxy-server=host:port
    Specify the HTTP/SOCKS4/SOCKS5 proxy server to use for requests. This overrides any environment variables or settings picked via the options dialog. An individual proxy server is specified using the format:
      [<proxy-scheme>://]<proxy-host>[:<proxy-port>] Where <proxy-scheme> is the protocol of the proxy server, and is one of:
      "http", "socks", "socks4", "socks5". If the <proxy-scheme> is omitted, it defaults to "http". Also note that "socks" is equivalent to "socks5". Examples:
      --proxy-server="foopy:99"
          Use the HTTP proxy "foopy:99" to load all URLs.
      --proxy-server="socks://foobar:1080"
          Use the SOCKS v5 proxy "foobar:1080" to load all URLs.
      --proxy-server="socks4://foobar:1080"
          Use the SOCKS v4 proxy "foobar:1080" to load all URLs.
      --proxy-server="socks5://foobar:66"
          Use the SOCKS v5 proxy "foobar:66" to load all URLs. It is also possible to specify a separate proxy server for different URL types, by prefixing the proxy server specifier with a URL specifier: Example:
      --proxy-server="https=proxy1:80;http=socks4://baz:1080"
          Load https://* URLs using the HTTP proxy "proxy1:80". And load http://*
          URLs using the SOCKS v4 proxy "baz:1080".

--no-proxy-server
    Disables the proxy server. Overrides any environment variables or settings picked via the options dialog.

--proxy-auto-detect
    Autodetect proxy configuration. Overrides any environment variables or settings picked via the options dialog.

--proxy-pac-url=URL
    Specify proxy autoconfiguration URL. Overrides any environment variables or settings picked via the options dialog.

--password-store=<basic|gnome|kwallet>
    Set the password store to use. The default is to automatically detect based on the desktop environment. basic selects the built in, unencrypted password store. gnome selects Gnome keyring. kwallet selects (KDE) KWallet. (Note that KWallet may not work reliably outside KDE.)

--version
    Show version information.

As a GTK+ app, Chromium also obeys GTK+ command-line flags, such as --display. See the GTK documentation for more:

    <http://library.gnome.org/devel/gtk/stable/gtk-running.html> <http://library.gnome.org/devel/gtk/stable/gtk-x11.html>

ENVIRONMENT
Chromium obeys the following environment variables:

all_proxy
    Shorthand for specifying all of http_proxy, https_proxy, ftp_proxy

http_proxy, https_proxy, ftp_proxy
    The proxy servers used for HTTP, HTTPS, and FTP. Note: because Gnome/KDE proxy settings may propagate into these variables in some terminals, this variable is ignored (in preference for actual system proxy settings) when running under Gnome or KDE. Use the command-line flags to set these when you want to force their values.

auto_proxy
    Specify proxy autoconfiguration. Defined and empty autodetects; otherwise, it should be an autoconfig URL. But see above note about Gnome/KDE.

SOCKS_SERVER
    SOCKS proxy server (defaults to SOCKS v4, also set SOCKS_VERSION=5 to use SOCKS v5).

no_proxy
    Comma separated list of hosts or patterns to bypass proxying.

FILES

~/.config/chromium
    Default directory for configuration data.

~/.cache/chromium
    Default directory for cache data. (Why? See <http://standards.freedesktop.org/basedir-spec/latest/> .)
