[FIXED] using sudo inside jupyter notebook's cell

Issue

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.

---

1:

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))

2:

 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.

3:

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.
