the web browser from Google
chromium [OPTION] [PATH|URL]
See the Google Chrome help center for help on using the browser.
chromium has hundreds of undocumented command-line flags that are added
and removed at the whim of the developers. Here, we document rela‐
tively stable flags.
-h or --help
Show help output.
-g or --debug
Start a debugging session within /usr/bin/gdb.
Use a throw-away/temporary profile for this session. This cre‐
ates an entirely new user profile temporarily. It is not the
same as incognito mode.
Allow installation and updates of remote extensions.
Specifies the directory that user data (your "profile") is kept
in. Defaults to $HOME/.config/chromium . Separate instances of
chromium must use separate user data directories; repeated invo‐
cations of chromium will reuse an existing process for a given
user data directory.
Runs URL in "app mode": with no browser toolbars.
Open in incognito mode.
If PATH or URL is given, open it in a new window.
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 us‐
ing the format:
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 ac‐ tual 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_VER‐ SION=5 to use SOCKS v5). no_proxy Comma separated list of hosts or patterns to bypass proxying.
Default directory for configuration data.
Default directory for cache data. (Why? See
