chromium - the web browser from Google
chromium [OPTION] [PATH|URL]
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.
Chromium Web Browser 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 $HOME/.config/chromium . Separate instances of
      Chromium Web Browser must use separate user data directories; repeated
      invocations of chromium will reuse an existing process for a given user
      data directory.
    
  
 
  - --incognito
 
  - Open in incognito mode.
    
  
 
  - --new-window
 
  - If PATH or URL is given, open it in a new window.
    
  
 
  - --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 Web Browser 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>
    
  
 
Chromium Web Browser 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.
    
  
 
  - $HOME/.config/chromium
 
  - Default directory for configuration data.
    
  
 
  - $HOME/.cache/chromium
 
  - Default directory for cache data. (Why? See
      <http://standards.freedesktop.org/basedir-spec/latest/> .)
