There are different ways to customize the name by which you can launch an application:
Method 1 - Create an alias Next to all options given in the other answers, a convenient way to make it easier for you to start Chrome from the command line, and which does not require to be administrator, is to create an alias:
Add this command to your
.bashrc file (already, some other aliases are defined there), so it is available anytime.
Method 2 - Create a symlink also does not require root permissions: you can create your personal
bin folder in your home directory. There, create a symbolic link to the executable of Google Chrome as:
ln -s /usr/bin/google-chrome ~/bin/chrome
On Ubuntu, a local
bin folder is automatically added to the PATH. After creating the bin folder, it will take only effect after your next log in.
Method 3 - Create a systemwide symlink If the change is to affect all users, create an appropriately named symlink in /usr/bin. As mentioned in the other answers, a symlink may already be available. If you prefer the shorter name
chrome, feel free to create an additional symlink as
sudo ln -s /usr/bin/google-chrome /usr/bin/chrome
or rename the existing symlink.
