I am making a script that will update my system (and do some other things, but that doesn't matter). I want the script to run sudo apt-get update
and sudo apt-get dist-upgrade --yes
automatically. I use --yes so I won't have to choose yes when it runs; it upgrades all packages automatically without me having to do anything. That said, I want to put my password in the script somehow so I won't have to type in my password when I run it either, probably with an argument or something. You know, something I can put at the end like sudo apt-get update --passwd MYPASSWORDHERE
. I have tried that and it doesn't work, but that's an example of what I want. What argument (--passwd or --password or something) do I put at the end to do this?

This has nothing to do with updating my system; I just want to know how to have the password put in automatically when using sudo in a script.– John ScottJul 10, 2014 at 21:20

I meant about you saying it was a duplicate in your first comment; not your second comment. :P– John ScottJul 11, 2014 at 0:34

If your script runs as "yourUser", you could create a simple file:
sudo visudo -f /etc/sudoers.d/myOverrides
with this directive:
yourUser ALL = NOPASSWD:/usr/bin/apt-get
You can find an useful explanation here.
Sudo doesn't behave that way, for security reasons. You can echo the password to sudo using the -s option, but I don't suggest it. Even if you protect your script from other users, they can still see your parameters using e.g. ps -ef
.
I think your problem is better solved by installing the unattended-upgrades package.
