[SOLVED] using sudo inside jupyter notebook's cell

using sudo inside jupyter notebook's cell

I'm trying to make a tutorial for a platform inside a jupyter notebook

at some point I need to run a linux command inside a cell like this :

!sudo apt-get install blah

but cant figure out how to enter the sudo pass , and I dont want to run jupyter notebook with sudo, any idea how to do this ?

Solution

Update: I checked all the methods, all of them are working.

Request password using getpass module which essentially hides input by user and then run sudo command in python.

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" #can be any command but don't forget -S as it enables input from stdin
 os.system('echo %s | %s' % (password, command))

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" # can be any command but don't forget -S as it enables input from stdin
 os.popen(command, 'w').write(password+'\n') # newline char is important otherwise prompt will wait for you to manually perform newline

NOTE for above methods:

The field where you enter the password may not appear in the ipython notebook. It appears in the terminal window on a mac, and I imagine it will appear in a command shell on a PC. Even the result details would appear in the terminal.

You can store your password in mypasswordfile file and just type in cell :

!sudo -S apt-get install blah < /pathto/mypasswordfile # again -S is important here

I would prefer this method if I want to view output of the command in jupyter notebook itself.
