Bash scripting and executable scripting

  • 772

I'm trying to run django combined with Jupyter in a virtual environment. The following code gets the job done:

source home/sujith/dev/django/bin/activate  && python home/sujith/dev/django/src/manage.py shell_plus --notebook

I saved the script as django.sh in my home directory. If I run ./django.sh the notebook pops up.

I tried saving this in /bin, but I couldn't run it. I want to type django instead of ./django.sh in my terminal and have the above script run.

How can I achieve this?

scripts command-line bash

    As ponsfrilus said, you must use absolute paths (paths starting with /) for your commands to work from /bin or /usr/local/bin. So your script should become:

    source /home/sujith/dev/django/bin/activate && python /home/sujith/dev/django/src/manage.py shell_plus --notebook

    To run it as django, you must save your script in a file named django with #/bin/bash on the top of the file. Then make it executable by running:

    chmod u+x /path/to/django

    where /path/to/django is the absolute path to your script.

    Finally, move your script to /bin by running:

    sudo mv /path/to/django /bin

    You should now be able to run your script just by typing django in your terminal.

    Another, much simpler, option is to create an alias for your script, by adding the following at the end of your .bashrc file:

    alias django='source /home/sujith/dev/django/bin/activate && python /home/sujith/dev/django/src/manage.py shell_plus --notebook'

    Then close your terminal and reopen it or run the following for the alias to take effect:

    source .bashrc
