script

%%script:
    Run a cell via a shell command

    The `%%script` line is like the #! line of script,
    specifying a program (bash, perl, ruby, etc.) with which to run.

    The rest of the cell is run by that program.

%%script is a cell magic that can be used to run scripts other than Python in your shell, like Bash, Perl, Ruby, or different versions of Python.

Each language has a shortcut, so %%ruby is the equivalent of %%script ruby, %%bash is the equivalent of %%script bash, etc.
