Ubuntu – Ubuntu Chromium browser – how to define zoom percentage via command line launch

Execute the following command in terminal,to change the default browser.

sudo update-alternatives --config x-www-browser

Sample output:

karthick@Ubuntu-desktop:~$ sudo update-alternatives --config x-www-browser 
There are 3 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /usr/bin/google-chrome   200       auto mode
* 1            /usr/bin/firefox         40        manual mode
  2            /usr/bin/google-chrome   200       manual mode
  3            /usr/bin/opera           90        manual mode

• Press enter to keep the default[*].

• Right now I have firefox as my default web browser.

• If i want google-chrome as default browser then I will type 3 and hit enter.

Note:

• If you want to configure a commandline browser,then you have to configure

  sudo update-alternatives --config www-browser

• Alternate way is to add the following line export BROWSER=/usr/bin/firefox to your ~/.bashrc

• Add the above line in the last,

  

Alternative GUI Method:

• You can also set the default browser in Gnome applications,type the following in terminal and press Enter gnome-default-applications-properties
• It will Open a Window.Now you can choose your preferred browser to set it default.

Yes, there is a --disable-translate switch that can be passed from the command line.

google-chrome --kiosk www.france.fr

google-chrome --disable-translate --kiosk www.france.fr

Note: some extra information I found is that if there's already another instance of Chrome running, running it from the command-line will show Created new window in existing browser session, which has proved to ignore the switches passed in the command, so you won't be able to pass the --disable-translate switch, so you'll need to close all instances first. However, if you want to run a new instance from the command line alongside the existing instance, you can do google-chrome --user-data-dir=$(mktemp -d) --kiosk --disable-translate (or another directory). This involves the creation of a new user data directory.

There are lots of other switches available in Chrome/Chromium that can be used. You can find them listed here and here.
