Install an application so that it can be launched from the terminal

  • 772

I had to update my Firefox from ver 3 (i.e. the one that Ubuntu 10.04 ships with) and move it to Firefox 7.
So firefox gave a tar.gz file to extract the browser from. I ran sudo apt-get remove firefox, and then extracted the contents of the tarball to /opt/. But when i type the command firefox in the terminal it responds by saying firefox not installed. I am now using a launch shortcut to open firefox, but what i want to know is
How can I install the application so that I can open it from the terminal?

    The programs to be executed are searched in the directories defined in the environment variable PATH. You can see what you have defined using:

    $ cat $PATH

    Assuming you have the executable available in /opt/firefox/bin, then you can do:

    $ export PATH=$PATH:/opt/firefox/bin

    To make permanent, you have to add that line it in your ~/.bashrc.

  2. For a single user:

    ln -s /path/to/firefox ~/bin/firefox

    For all users:

    sudo ln -s /path/to/firefox /usr/bin/firefox
