I opened a program via linux terminal, and after some search in Google I find out that I can close the program by Ctrl+C. If I want to run the program, but at the same time have a new line in the command terminal (like I have when I close the program) to do some other work.  Is there any shortcut key?
When you are performing time consuming operations in bash like installing new software, is it possible to write text that will appear at the prompt when the operation has finished.  E.g   Imagine running:  apt-get install eclipse-platform   Then it will use quite a while to finish while you see the installation log, meanwhile I want to create new folders (workspaces) which Eclipse later will use.  Is this possible without opening a new terminal (or tab)?

Taxonomy count per Post type Below is the code i use to output the post tag (taxonomy) count/number.

In the season 5 finale of Doctor Who, in the wedding ceremony of Amy, River Song showed up outside the door. Moments later, we discovered that she gifted Amy her blank diary which was supposed to contain information about The Doctor. It means River Song remembered The Doctor.

How to get from Heathrow Airport to King's Cross, London? My wife and I will be arriving in London via Heathrow Airport (LHR) and are staying at a hotel near King's Cross station. So, we were wondering what the best (which means fastest but also easiest when carrying two large pieces of luggage and two carry-ons) way to get from LHR to King's Cross?  I gather that, with only one changeover, we can take the Tube. However, in the interest of other passengers, we thought it would be best to take a taxi, or maybe a bus?

Is there a function whose inverse is exactly the reciprocal of the function, that is $f^{-1} = \frac{1}{f}$? Is there a function whose inverse is exactly the reciprocal of the function? That is $f^{-1} = \frac{1}{f}$.  We know that the inverse of a function is not necessarily equal to its reciprocal in general. Does English allow a zero copula in subordinate clauses? In a casual search of the web, I found a few indications English does not allow zero copulas ().  However, I frequently see sentences with subordinate clauses that juxtapose a noun phrase with an adverb phrase, such as the following from a contemporary sci-fi author:  Kai stares up at me from the grave, his eyes hard as obsidian.  If this clause were made into a sentence, it would take an obligatory verb:  *His eyes hard as obsidian.  His eyes are hard as obsidian.  The original clause seems to contain an implicit "to be."  Is it an example of a zero copula?  If not, what is this construction called? How long can eggs be unrefrigerated before becoming unsafe to eat? I just renewed my antivirus (Kaspersky's) yesterday.
