[SOLVED] Require authentication before my script executes

broi · 2012-03-24 23:03:09

OK I got a little bash script where I type in how many minutes my computer will poweroff.
Normally, it can be ran with regular user even the code contains command "poweroff" which requires root privilegies so, when times up, instead of poweroff, I get message: "poweroff: must be superuser"

Now, I want it to be like, when I run it (./myscript) to require authentication before the script even start like, for example Gparted requires, so if an authentication passes, my scirpt can run and have permission to do whatever it's written in it (in this case, 'poweroff').

Thanks ^_^

This snippet checks if you've sudo-ed it (or ran as root). All subsequent commands can be coded without sudo.

Thank you very much!
Another solution would be executing your script with pkexec [scriptname], so you get GUI authenticaion requirement.

Or you can invoke D-Bus as regular user to shutdown your computer.

Or you can add poweroff, or your script name to your sudoers file to not need a password.
