jupyter_mac.command is not executable with fish.

[hal0taso]

Actual Behavior

Getting following error when I launch Jupyter-notebook via Anaconda-Navigator.

/Users/hal0taso/anaconda3/bin/jupyter_mac.command ; exit;
Failed to execute process '/Users/hal0taso/anaconda3/bin/jupyter_mac.command'. Reason:
exec: Exec format error
The file '/Users/hal0taso/anaconda3/bin/jupyter_mac.command' is marked as an executable but could not be run by the operating system.

and Jupyter-notebook does not launch.

Expected Behavior

execute jupyter_mac.command, and it should be launch jupyter-notebook

Steps to Reproduce

jupyter_mac.command is following script.

DIR=$(dirname $0)

$DIR/jupyter-notebook

This script only executes jupyter-notebook on same directory but doesn't assign which interpreter it uses.

so when you execute this script with fish, you can get this error.

(My login shell is fish, so it doesn't work. When I execute jupyter_mac.command via sh or bash, it work.)

I think we'd better add shebang like #!/bin/sh on first line.

@hal0taso I had the same issue on my macOS and I resolved it by adding the following line on the top of anaconda3/bin/jupyter_mac.command
#!/bin/bash
Hopefully this helps.

[hal0taso]

@scarlet-ethan-lin Thank you for your reply! I already solved this issue, but I suggest to add shebang because Anaconda is a widely used project.

I think users should be able to use these useful tools without any consideration of what login shell they use. (It is true that users who change their login shell will can solve these trivial issue themselves, but it is little inconvenient.)

[BadToast]

@scarlet-ethan-lin @hal0taso I suggest updating the script as well. Otherwise you'll get warnings about your Anaconda/Notebook being corrupt because the hashes no longer match due to your changes:

SafetyError: The package for notebook located at /usr/local/anaconda3/pkgs/notebook-5.5.0-py36_0
appears to be corrupted. The path 'bin/jupyter_mac.command'
