I have installed the astronomy software CASA in my computer, and I would like to be able to run it from any directory just by typing casa in the Ubuntu terminal. What should I change so that this is possible? I've tried the following:

sudo ln -s ./home/alcrespe/Desktop/casa-prerelease-4.7.0-22/bin/casa ./usr/bin/casa

... but it doesn't work. I'm no expert in Ubuntu, how can I fix this? As the previous line suggests, so far I can only access the program CASA in the following location:

./home/alcrespe/Desktop/casa-prerelease-4.7.0-22/bin/casa

You have two issues to address from my finds:

  1. Doing it right:

    • You are obviously not following the steps correctly as I did and have successfully ran it using casa command, though the link says casapy.

    • Solution please follow the steps verbatim.

      • sudo mkdir /usr/local/bin/CASA
      • sudo mv casapy-30.0.9860-001-64b.tar.gz /usr/local/bin/CASA
      • cd /usr/local/bin/CASA
      • sudo tar zxvf casapy-30.0.9860-001-64b.tar.gz
      • Add this to your ~/.bashrc file and then source it with source ~/.bashrc:
        • export PATH=$PATH:/usr/local/bin/CASA/casapy-30.0.9860-001-64b/bin
      • Test it with: casa

      • Output:

         george@george-ubuntu-server:~$ casa

 CASA <2>:

  2. Library issues. The latest version works on Ubuntu Xenial, and the version your installing might not work on your version of Ubuntu as I discovered when I tried to install your version 4.* on it. So get back to your instructor for further help.

Important Note:

You might want to install it on a Virtual Device as I noticed your version insisted on creating a user with id 1001 irrespective of who owns that id. In my case the user koko was made the group owner of the /usr/local/bin/CASA/* directory. Permission given to folder: 

drwxr-xr-x 11  12998   1001      4096 Jan  5 06:09 casa-stable-5.0.101/

Change the casapy-30.0.9860-001-64b to the one you download or the name seen there after extraction
