comment How to easily execute last output line in bash?
Your now-deleted answer to the related Ask Ubuntu question looked potentially quite useful. Provided the utility you recommended really does have this particular feature, I suggest editing your answer for clarification and undeleting it. You needn't worry about the downvotes--once the post clearly shows that the method works and how to use it, they might be reversed--and even if not, it'll get at least my upvote, and probably others.

comment How to remove all the parts of a split RAR archive file using command line?
But rm (without -r) also excludes directories. This find way has no advantage over rm filename.r*, which fswings is trying to improve upon. rm filename.r* deletes as much as the OP wants to delete (and possibly more); this method with find deletes at least as much as rm filename.r*, and sometimes more since find is recursive (i.e., it descends into subdirectories and deletes files there, and in their subdirectories, etc.). You could confine it to operating on the contents of . by adding -maxdepth 1, but it still wouldn't have any advantages over rm filename.r*.

comment Sudo vs root; any actual differences?
sds, @CharlesDuffy: The idea that sudo and su cause geteuid() and getuid() to be different from one another is a myth. su and sudo change both the real and effective user IDs to those of the target user before running the specified command or shell, except in the very unusual situation that you've explicitly configured them to behave otherwise. You can verify this (for sudo) by running sudo id -u and sudo id -ru (both show 0), reading sudo(8) (under COMMAND EXECUTION), or writing a test program.

comment Can I burn a CD ISO to DVD?
Burning an ISO to a DVD that will fit on a CD is not necessarily a waste: the same will drive will almost always read any DVD faster than any CD.

comment How do I create an administrator user on Ubuntu?
I know this is an old answer, but for the benefit of people coming here now: By default in Ubuntu, no wheel group exists, and this is not how administrative abilities are conferred. The sudo group is used (or the admin group -- not to be confused with the other group called adm -- in Ubuntu 11.10 and earlier).

comment What's the equivalent of Ubuntu's apt-get command on a Mac
The Fink project provides apt-get for OS X. So you may want to use that. This is really off-topic for Stack Overflow (or marginally on-topic as it pertains peripherally to install Ruby gems), so I recommend asking on Unix.SE or Ask Different instead. (Please read their FAQs and consider which would be appropriate given your question.)
