bash script ask for root password

Question

I want have a script that I can give to friends which will add repositories and download files, install them without having to use command as they are not command line savey and have no desire to learn. I need to know how to get the script to prompt them for the root password to allow them to do some of these functions. How would I go about this? Please don't hate on them.. Getting them to start using Linux was a big step and I am just happy that they are attempting something new... and it was in the open source world..

Answer 1

Just use the sudo word in front of the command in the bash script. And when you execute the file, select "Open in terminal", you will be asked for password.

For example, if you are using apt-get commands , you can use like this

#!/bin/sh
sudo apt-get update
sudo apt-get upgrade
.....
.....

If need to make this executable and when you double click there will be a prompt like this

You need to click on Open in terminal button and provide password in the terminal

Update

As Karthick T commented, you can also use the gksu or gksudo word before the command. So, the file could be

gksu apt-get update
gksudo apt-get install <some-package>

Double clicking the script will ask the password and run the command after you provided it.
