I would like to add a directory to my path, in my IBM server running Ubuntu 22.04. I would like to install the genome assembly software, SuperNova-2.1.1 by 10x genomics. In order to start using their supernova command, I must add the directory to my path. The path was added using the following command:

export PATH=/opt/supernova-2.1.1:$PATH

They have also suggested adding the path to .bashrc, which I don't know how to perform. Anyways, the problem is when I try to invoke their supernova command, the prompt says command 'supernova' not found. Can someone help me understand the problem, and how to add the command to the .bashrc?

NB: The details on how to navigate through the installation can be found here.

  • "adding the path to .bashrc, which I don't know how to perform" you just open the file in any text editor, and type your changes - see for example Permanent PATH variable – steeldriver Feb 21 '23 at 12:04
  • Welcome to Ask Ubuntu! Does it work if you run /opt/supernova-2.1.1/supernova? If not, then it isn't installed properly, and adding it to the path isn't going to help. – NotTheDr01ds Feb 21 '23 at 15:54

    Also a question - You have this tagged [tag:windows-subsystem-for-linux], but you mention that you are running Ubuntu on your "IBM server". This doesn't quite match up. WSL is a Microsoft feature for running Ubuntu under Windows, not on an IBM server. It probably doesn't matter for this question, but you may want to clarify or remove the WSL tag. Thanks! – NotTheDr01ds Feb 21 '23 at 15:55
  • Thanks for the response. Actually, the problem was resolved by invoking the supernova command as follows: ./supernova – VIJITH KUMAR Feb 22 '23 at 07:09
