Okay, so I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success.

My other question is if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as: now how would I get the script to insert my wanted password.

This script is something that I want to be run under cron, that's why I ask.

I am running Fedora 15.

I would script it like this:
Compare the time and if it is not time sleep a minute or some seconds in a loop.

for executing programms there you can set a group for that programm and you get a member of it. So there is no need to sudo.

Because the shell that needs the passord is running, your current script is sleeping the while and can not do anything (not submit a password). So there is no possibility to give passwords automaticaly !!!

If you are looking for question and answer type scripting you can have a look at expect.

I am sorry Bastl, I don't understand what you are say. This is probably my fault.
My Main problem is the automated user input. I checked out Expect, and I don't know how that can be used in my situation. My example was one was the things I am doing. It was That is the code to make a zip file, and encrypt it with a password. I want my script to do this, along with some other file stuff. My problem comes when I want to encrypt the file. I have no way to set what the password will be.

Then you have to read the manual for your encryption programm that you use for your zip archives.
Maybe you have an option that takes your password, but I think no, because this would be a big security lack.

Well the program that I use is just called zip. It came with Fedora. Normally when you use it just like in a terminal, when you enter the command it asks for the wanted password, asks it again, then the entered password is required to unzip the file. The password that I intend on using is the same as my root password, so maybe that'll help. But all I need is a way to make the zip files require a password with out me entering the password.

I guess fedora uses GnuPG for file encryption.
Like I read does fedora has fundamental encryption mechanisms. Maybe you can use them for your task.
Read also about VPN, SSH tunnel-ing and LUKS.
Your task can get very fedora specific. So you should look what your system setup about encryption is (init, kernel, ...).
Then you can ask more detailed questions.
At the moment it looks like I described it in my first post, that the password request is needed and your script is not running (idle) at that time, so you can not enter a password automatically.
This is because of the high security standard you want, too. You also encrypt your zip archives and that should make sense.
Maybe you want to take zip archives out of that encryption mechanism (if you don't have a full encrypted system (harddisk)).

I'd simply add the one command you wish to run as a different user (root?)
to your sudoers file w/ a NOPASSWD:


Plain and elegant.

Okay, and how would one go about doing that? Sorry if it sounds stupid.

You type:
visudo
You find the line that describes you.
You add at the end of it NOPASSWD: /path/to/command *
You save.
You enjoy.

I tried that and my name is not mentioned in the file at all. I even opened it up in Gedit and searched it for "jetso" and nothing. I know I am in the sudoer's file though. I use sudo under jetso all the time.

What about group memberships?

This is probably gonna sound stupid, but what? Should I post a copy of the sudoers files?

Can you not just add it to root's crontab?

You could do that; or you could embrace the learning opportunity,
and learn about the "id" command.

Try id -a <your_username>. Look at the groups it lists.
Try to find one of those in sudoers.
