• BASH Scripting: Check If running with sudo/superuser, if not, dont run, return error

  - by EvilPhoenix

  This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?

• PPA & Packaging: Having versions of packages for multiple distros

  - by EvilPhoenix

  (quote from chat) Got a PPA on launchpad for source packages for an IRC bot project I'm associated with (since its all the intermediate packaging for the stuff between releases, it's classified as an "experimental" PPA). Question: I've already packaged the stuff for a lucid build. Any clue how I'd be able to create the same packaging, except package it for maverick, and put it up to the same PPA that I've put the lucid packaging to?

• Why is there a lack of Backports of Optional 10.10 or later Packages in repos?

  - by EvilPhoenix

  This question is about backports again, but is specific to the difference in availability of packages. A specific example of this would be the two gcc packages in 10.10's repos: gcc (which is 4.4), and gcc-4.5 (which is gcc 4.5). While this change is in 10.10's repositories, such optional packages aren't included in the 10.04 LTS repositories, and the option to have a gcc-4.5 compiler in 10.04 might help several people (such as myself, who needs the 4.5 compiler for University, and I can't upgrade to 10.10 because it doesnt operate correctly on my system). Is there a reason a lack of such optional packages is in the 10.04 repositories?
