How to run shell script file on ipython at Google Colab

Question

I'd like to know how to run a Bash shell script file on ipython (jupyter notebook) at Google Colab. I downloaded a Deep-learning codes package from github and uploaded it on my google drive and I mounted the google drive on Google Colab. The code package includes '*.py' python codes and 'fn.sh' script file. By executing the script file the python codes can be executed.

I tried os.system('fn.sh') and subprocess.call('fn.sh') on the ipython prompt at Google Colab but they doesn't work like below.

import os
os.system('drive/DL/denet-master/examples/simple-cifar10.sh')

import subprocess
subprocess.call('drive/DL/denet-master/examples/simple-cifar10.sh')
OSError: [Errno 8] Exec format error: 'drive/DL/denet-master/examples/simple-cifar10.sh'

Answer 1

In Colab, you can invoke shell commands using either ! or %%shell.

Your invocation above would be:

!drive/DL/denet-master/examples/simple-cifar10.sh

Here's an example notebook:
