Ubuntu: Adding 'soft link' to julia



Question:

I would like to be able to open the software "Julia" by simply typing 'julia' in a terminal at any location (like I can do for, say, firefox). Currently I have to type

cd ~/julia  ./julia  

According to the documentation I must:

Add a soft link to the julia executable in the julia directory to /usr/local/bin (or any suitable directory already in your path).

I don't fully understand softlinks, but I can't figure out why this doesn't work:

ln -s ~/julia /usr/local/bin

Why won't this allow me to access the contents of the ~/julia file (including the julia executable) directly?

Thanks!


Solution:1

I assume the executable julia is under ~/julia/ folder. Use the following command in terminal to make a softlink in /usr/local/bin,

sudo ln -s /home/<username>/julia/julia /usr/local/bin  

Replace <username> with your actual username. Or,

sudo ln -s "$HOME"/julia/julia /usr/local/bin  

Note: you need to use sudo to access /usr/local/bin as it is system directory.

Alternate User level Method (if you do not have root access)

You can create a folder $HOME/bin and put it in path, use the following commands in terminal,

cd  mkdir bin  echo "export PATH=\$HOME/bin:\$PATH" >> ~/.bashrc  . ~/.bashrc  

Now create a softlink in $HOME/bin as,

ln -s "$HOME"/julia/julia "$HOME"/bin  


Solution:2

You can also just right click on the Julia file and navigate to Make Link then copy the newly created link to anywhere on your home directory.
