nbopen minimal

Minimal viable solution for always launching notebooks on the same notebook server.

Advantages:

• Simple to use
• Aggregates launched notebooks on single notebook server
• No software to install

Disadvantages:

• Server directory is hard coded (default is /, change at will)
• Server port is hard coded (default is 8888, change at will)
• No guarantee that it works AS-IS on your machine. I wrote it up on a OSX. You may have to make a few changes to get it working on Linux, such as exchanging open with xdg-open.

Usage

Create new notebook server if none exists:

$ nbopen

Open a notebook. If no notebook server exists, one is created:

$ nbopen path/to/my/notebook.ipynb

"Installation"

Copy the following code into your .alias file and source it:

function nbopen(){
    if [ $# -eq 0 ] ; then
        if lsof -Pi :8888 -sTCP:LISTEN -t > /dev/null ; then
            echo "A Jupyter Notebook is already open on port 8888"
        else
            jupyter notebook --notebook-dir / --port 8888
        fi
    else
        if [ "${1:0:1}" != "/" ] ; then
            address=$(pwd)/$1
        else
            address=$1
        fi
        if lsof -Pi :8888 -sTCP:LISTEN -t > /dev/null ; then
            open http://localhost:8888/tree"$address"
        else
            jupyter notebook "$address" --notebook-dir / --port 8888
        fi
    fi
}

If you don't maintain a .alias file, chances are have a .profile file which is sourced at boot. You can put the code there. Remember to source it (like source .profile).

Also, if you already have the original nbopen program written by takluyver installed, you should give the function a different name, like nbopen_min or something.
