What is Games in man page
What do the numbers in a man page mean?
I've got bunch of files with ill-formed numbering:  prefix-#.ext       | for files with number 1-9 prefix-##.ext      | for files with number 10-99 prefix-###.ext     | for files with number 100-999   Due to further processing I need all of their names to be in format: prefix-###.ext. Is there any easy way to do that? Proof $p \vdash q \Rightarrow p$ Firstly, how do I read it? Is below right? With braces   $$p \vdash (q \Rightarrow p)$$  The given proof is:    ${p}$, premise ${q}$, assumption  $p$ by (1) // what???  ${q} \Rightarrow p$ by implication introduction with 2 and 2.1 QED...    I can't really get the link between $p$ and $q$ in 2.1 ... Within a set of directories, how do I find a file whose name includes a given string, such as "abcde"? Let $S$ and $T$ be finite non-empty sets such that $|S| = |T|$. Show that the function $f : S\to T$ is onto if and only if it is one-to-one. This is a recent homework bonus question assigned in my Proofs and Conjectures class. It (evidently) includes and evaluates our understanding of elementary-set theory and how to determine and prove that the function f is onto and one-to-one. I haven't been able to really grasp firmly how it is we do this. Help would be much appreciate, thank you. I use Lyx 2.1, document class : Report. My problem is that the titles of figures are written on the numbers at List of Figures. Simple chessboard exercise 64 bit enum in C++? Is there a way to have a 64 bit enum in C++?  Whilst refactoring some code I came across bunch of #defines which would be better as an enum, but being greater than 32 bit causes the compiler to error.  For some reason I thought the following might work:  enum MY_ENUM : unsigned __int64   {       LARGE_VALUE = 0x1000000000000000,   }; Why are second order linear PDEs classified as either elliptic, hyperbolic or parabolic? Is there a geometric interpretation of second order linear partial differential equations which explains why they are classified as either elliptic, hyperbolic or parabolic, or is this just a naming convention? That is, do they have any relation with actual ellipses, hyperbolas and parabolas? Show that the polynomial $X^5 + X^3 + \bar{1}$ in $(\mathbb{Z}/2\mathbb{Z}[X])$ is irreducible What's the difference between absolute path &amp; relative path when using any web server or Tomcat? Book about almost extinct warrior race with three castes: sen, kaa, ker The aliens in this book are an humanoid alien mercenary race, fighting for some other aliens, against humans?.   The Ker are the fighters, the sen are the wise ones, and the kaa the family/non-fighters.  Their clan gets almost wiped out because both their employers and humanity fear them, and the last survivors head towards their race' home planet, together with a human captive, who learns about their ways.  The other aliens are some blob-like aliens with little genetic variety.  Ring any bells? How to visualize Reverse Triangle Inequality $||\mathbf{a}| − |\mathbf{b}|| ≤ |\mathbf{a} − \mathbf{b}|$? pp  and ,   illustrates Triangle Inequality. But without referring to Triangle Inequality at all, how to picture  Reverse Triangle Inequality for all $\mathbf{a,b} \in C^n$? I don't want proofs or rigour. Regular expression to extract URL from an HTML link I’m a newbie in Python. I’m learning regexes, but I need help here.  Here comes the HTML source:  &lt;a href="http://www.ptop.se" target="_blank"&gt;http://www.ptop.se&lt;/a&gt;   I’m trying to code a tool that only prints out http://ptop.se. Can you help me please? Since I can't find any alternative to Linux'  elevation command, I have the following question:  How to define a PowerShell function which requires elevation? I mean UAC prompt.  Say, such function follows:  function system-check {     SFC /ScanNow }   System:  Windows 8.1 Pro 64-bit  PowerShell:   Major  Minor  Build  Revision -----  -----  -----  -------- 5      0      10586  117    EDIT1:  To be 100% understandable let me rephrase:   I run PowerShell as user I run the aforementioned function system-check I want the function to elevate in order to be able to execute the command; note, that I want the UAC prompt to appear My last name is not the same on ticket as on passport; rest of details are same How can I automatically determine fonts used in an image or PDF? Can you forgo your readied action to take an opportunity attack instead? Example:   Player 1 uses the ready action to do something when something happens (unimportant) Goblin, decides to charge across the battlefield and attack Player 2, but happens to cross paths with Player 1 possibly provoking an opportunity attack (here lies my question)   Could Player 1 decide to ignore their readied action and use their reaction to attack the goblin? This would of course take up their reaction so they could no longer take their readied action when it triggers.  If so; let's say it is a fireball that was readied (or any spell), would Player 1 be required to drop the fireball spell? They technically cast it as part of their ready action, but I would understand if this would be a downside to using a reaction before their readied action triggered (maybe this should be another question, but please answer it anyway and tell me if I need to create a separate one so you can answer it there too :P). Is my processor 64 or 32 bit? Why is spectrum obtained by sunlight, said to be continuous? My teacher spoke about atomic spectra today, and he explained that, unlike the spectrum obtained by analyzing the sunlight, the spectra of atoms are not continuous.     I have a question about this - even the sunlight has the radiations emitted by the atoms of the elements which compose the sun, still spectra is continuous, which is in opposition to the statement that atomic spectra is discontinuous. So, spectrum obtained by sunlight is continuous even though it atomic spectra. In order to account for spectrum obtained by the sunlight to be continuous and atomic spectra to be discontinuous, can we confirm that sun consists of all those elements (sodium, helium, neon, mercury, etc) which emit the colors of frequency belonging to visible region? Which option is grammatical?        There will be readings from Nikki Giovanni’s and Alice Walker’s writings.   There will be readings from Nikki Giovanni and Alice Walker's writings.      Saying it out loud the latter sounds right, but looking at it the former looks better.
