comment bash script in unix - return full path and filename
Full path of what? Self, as in the full path of the running script or some other object? A text string passed to your script as an argument?

comment Space a valid delimiter for email addresses in email header?
As pauska noted in his edit, the RFC that describes how SMTP servers talk to eachother requires that recipients be expressed on separate lines behind their own RCPT command. However it is not clear to me that this is the question you are asking because the mime header data you show is not the chat between SMTP servers but your little package that you feed into a mailer that then interprets that and does all the SMTP talk with other mail servers according to RFC's for you. Can you clarify which part of that pipeline you are working with?

Well then :) If that oddity of administration IS your gig, then I guess you have to work with it. I do think I would look into some way of sandboxing the users to insulate themselves from harming the box, other users, and ultimately themselves. Some form of lightweight virtualization like vserver might do the trick allowing you to allocate resources more fairly overall while giving them unfettered shells. The little bit of overhead is probably worth it in stability/versatility. Automatically batching shell processes seems like a significant handicap scenario to me.

comment Linux Mdadm + LVM recovery
Thanks for posting your answer. How exactly did you blank the partition table? I'm a little confused seeing as how I run lvm on partitioned devices all the time. Did your raid array have partitions INSIDE itself?

comment What are XSAVE and /dev/xvda1
@paul, I'm a little confused myself but I think what happened is xvda1 etc has always been the device node inside Xen guests (xen virtual device a), however when Amazon started using it they patched the foo out of it so that devices on instances running any of the Amazon AKI's showed up as the more familiar sda. Now that we have the ability to run our own kernels and vendors are making their own, we're back to the standard set of Xen devices because our kernels are closer to stock.

Things you can think about however would be creating chroot environments so that users in the newbie group would only get a small subset of commands and a sort of sand box world to play in instead of being on the main track. Also perhaps just monitoring the process list of some users for long running or resource heavy jobs using some basic ps comands so you can nice or kill of unwanted jobs. I still assert that if you are more specific with what kind of jobs your users need to run we could offer better suggestions.

@arman: I think your analogy still breaks down. You're trying to dump guest and beginner users in an F1 car that is already going 150mph around the track DURING a race. It's just not a good idea. You don't give bumbling newbies shell accounts on production boxes.
