OPTIONS

       Google  Chrome has hundreds of undocumented command-line flags that are

       added and removed at the whim of the  developers.   Here,  we  document

       relatively stable flags.  



       ...



       --version

              Show version information.

So you can use the command google-chrome with the --version option:

google-chrome --version

gives:

    Google Chrome 36.0.1985.125

For the following commands, I am using grep and regex, because it is much more adaptable to changes in Google Chrome version format changes

To get just the version number run the following command:

google-chrome --version | grep -iE "[0-9.]{10,20}"

It gives:

    36.0.1985.125

And this one:

google-chrome --version | grep -iE " [0-9]{1,3}.[0-9]{1,3}

gives you just the main version numbers.

    36.0

If you have beta installed:

Running this command:

google-chrome-beta --version

gives:

Google Chrome 37.0.2062.58 beta

And then there are the gui methods:

You can go to the following sites:
